MRI Cervical Spine Abnormalities: Your Guide

Magnetic Resonance Imaging, commonly known as MRI, stands as a crucial diagnostic modality utilized by medical professionals, including those at institutions like the Mayo Clinic, to visualize the intricate structures of the cervical spine. These detailed images play a pivotal role in identifying a range of conditions, with the extent of abnormalities often being classified using standardized reporting systems, such as the modified Pfirrmann classification, to assess disc degeneration. Moreover, the interpretation of MRI results often requires expertise in neuroradiology to accurately differentiate between normal anatomical variations and pathological changes that might necessitate further investigation or intervention. Therefore, a comprehensive understanding of the application of MRI in evaluating cervical spine health is paramount for both clinicians and patients seeking clarity on the diagnostic process and potential treatment pathways for mri of cervical spine abnormalities.

Unveiling Cervical Spine Abnormalities with MRI

The cervical spine, a sophisticated and crucial component of the human skeletal system, warrants meticulous attention in medical diagnostics. This upper portion of the vertebral column, comprising seven vertebrae (C1-C7), is not merely a structural support but also a pivotal conduit for neural pathways and a facilitator of head movement.

Its health is paramount to overall well-being, and when abnormalities arise, precise identification becomes essential. Magnetic Resonance Imaging (MRI) has emerged as a cornerstone in visualizing and diagnosing cervical spine pathologies.

The Cervical Spine: Anatomy and Function

The cervical spine’s intricate design allows for a remarkable range of motion, enabling us to nod, rotate, and tilt our heads. This flexibility is made possible by the unique shape of the cervical vertebrae and the intervertebral discs that cushion them.

Beyond mobility, the cervical spine plays a crucial role in protecting the spinal cord, the delicate bundle of nerves that transmits signals between the brain and the rest of the body.

Key structures within this region include:

• Vertebrae: Provide bony protection and structural support.
• Intervertebral Discs: Act as shock absorbers between vertebrae.
• Ligaments: Connect vertebrae, providing stability.
• Spinal Canal: Encloses and protects the spinal cord.
• Nerve Roots: Emerge from the spinal cord, transmitting signals to the body.

MRI: A Window into the Cervical Spine

MRI employs strong magnetic fields and radio waves to generate detailed images of the body's internal structures. Unlike X-rays or CT scans, MRI does not use ionizing radiation, making it a safer option, especially for repeated imaging.

MRI excels in visualizing soft tissues, such as the spinal cord, intervertebral discs, and ligaments, which are often difficult to assess with other imaging modalities. This capability makes MRI particularly valuable in diagnosing cervical spine abnormalities.

Advantages of MRI

The advantages of MRI in cervical spine imaging are considerable:

• Superior Soft Tissue Contrast: MRI provides exceptional visualization of soft tissues, allowing for the detection of subtle abnormalities.
• Multiplanar Imaging: MRI can acquire images in multiple planes (axial, sagittal, coronal), providing a comprehensive view of the cervical spine.
• Non-Ionizing Radiation: MRI does not use ionizing radiation, reducing the risk of potential long-term health effects.
• Detection of Subtle Changes: MRI can detect early signs of disease, such as edema or inflammation, which may not be visible on other imaging modalities.

However, MRI also has its limitations.

It can be more time-consuming than other imaging techniques and may not be suitable for patients with certain metallic implants or devices. MRI safety protocols must be followed.

MRI Safety Protocols

Prioritizing patient safety in MRI demands strict adherence to established safety protocols. Before undergoing an MRI scan, patients are carefully screened for any contraindications, such as:

• Metallic Implants: Certain metallic implants, such as pacemakers or aneurysm clips, may be affected by the strong magnetic field.
• Allergies: Patients with known allergies to contrast agents should inform the medical staff.
• Pregnancy: The safety of MRI during pregnancy has not been definitively established.

Common Cervical Spine Abnormalities

MRI is instrumental in diagnosing a wide range of cervical spine abnormalities, including:

• Disc Herniation: Occurs when the soft, gel-like center of an intervertebral disc protrudes through the outer layer, potentially compressing nerve roots or the spinal cord.
• Spinal Stenosis: Narrowing of the spinal canal, which can compress the spinal cord and nerve roots.
• Spondylosis: Degenerative changes in the spine, including osteoarthritis, bone spurs, and disc degeneration.
• Myelopathy: Injury to the spinal cord, often caused by compression or inflammation.
• Radiculopathy: Compression or irritation of a nerve root, leading to pain, numbness, or weakness in the arm or hand.
• Fractures and Tumors: MRI can detect fractures and tumors affecting the cervical spine, aiding in diagnosis and treatment planning.

The Radiologist's Role

The radiologist plays a pivotal role in interpreting MRI images of the cervical spine. Their expertise is essential for:

• Image Interpretation: Accurately identifying and characterizing abnormalities on MRI scans.
• Differential Diagnosis: Considering various possible diagnoses based on the MRI findings.
• Clinical Correlation: Correlating MRI findings with the patient's clinical symptoms and medical history.
• Reporting: Communicating findings clearly and concisely to the referring physician.
• Clinical Decision-Making: Providing guidance on appropriate management strategies.

The radiologist's interpretation serves as a crucial guide for clinicians in formulating treatment plans tailored to each patient's unique needs.

Understanding Cervical Spine Anatomy and Normal MRI Appearance

To accurately interpret MRI scans of the cervical spine and identify pathologies, a solid understanding of normal anatomy and its corresponding appearance on MRI is paramount. This foundation is essential for differentiating between normal variations and pathological conditions, ensuring accurate diagnoses and appropriate clinical decision-making. We must be able to visualize the structures within the MRI to accurately assess for injury.

Cervical Vertebrae: Structure and Function (C1-C7)

The cervical spine, composed of seven vertebrae (C1-C7), is a complex and highly mobile region of the vertebral column. Each vertebra possesses unique features that contribute to the overall stability and range of motion of the neck.

C1, or the atlas, articulates with the occiput of the skull, allowing for nodding movements. C2, or the axis, features the odontoid process (dens), which articulates with the atlas, enabling rotational movements. The remaining cervical vertebrae (C3-C7) share common characteristics, including a vertebral body, pedicles, laminae, spinous process, and transverse processes. These vertebrae house the spinal cord and provide attachment points for muscles and ligaments.

Intervertebral Discs: Composition and Biomechanics

The intervertebral discs, located between the vertebral bodies, act as shock absorbers and contribute to spinal flexibility. Each disc consists of a central gelatinous nucleus pulposus surrounded by a tough, fibrous annulus fibrosus.

The nucleus pulposus is primarily composed of water and proteoglycans, providing resilience and cushioning. The annulus fibrosus consists of concentric layers of collagen fibers, providing tensile strength and resisting compressive forces. The intervertebral discs function to distribute loads evenly across the vertebral bodies and allow for a wide range of spinal movements.

Nerve Root Course and Distribution

Nerve roots emerge from the spinal cord and exit the vertebral column through the intervertebral foramina. In the cervical spine, each nerve root exits above the corresponding vertebral body (e.g., the C5 nerve root exits between C4 and C5).

These nerve roots innervate muscles, skin, and other tissues in the upper extremities and neck. Understanding the course and distribution of cervical nerve roots is critical for correlating MRI findings with specific neurological symptoms. Compression or irritation of a nerve root can result in radiculopathy, characterized by pain, numbness, or weakness in the affected dermatome or myotome.

Spinal Cord Anatomy within the Cervical Region

The spinal cord, a vital component of the central nervous system, traverses the cervical spine within the spinal canal. It is responsible for transmitting sensory and motor information between the brain and the rest of the body.

In the cervical region, the spinal cord is relatively large and contains a high concentration of nerve fibers. MRI allows for detailed visualization of the spinal cord, enabling assessment of its size, shape, and signal intensity. Abnormalities such as spinal cord compression, edema, or myelomalacia can be readily identified on MRI.

Normal MRI Signal Intensity Characteristics

MRI signal intensity is a crucial factor in distinguishing normal and abnormal structures within the cervical spine. Different tissues exhibit varying signal intensities on T1 and T2-weighted sequences, reflecting their composition and water content.

On T1-weighted images, vertebral bodies typically appear with intermediate signal intensity due to the presence of bone marrow. The intervertebral discs demonstrate relatively low signal intensity. The spinal cord appears with homogeneous intermediate signal intensity.

On T2-weighted images, vertebral bodies maintain intermediate signal intensity. The nucleus pulposus of the intervertebral discs exhibits high signal intensity due to its high water content. The annulus fibrosus appears with relatively low signal intensity. The spinal cord demonstrates homogeneous high signal intensity, allowing for clear visualization of its internal structures.

Appearance of Ligaments, Muscles, and Neurovascular Structures

In addition to the vertebral bodies, discs, and spinal cord, MRI provides detailed visualization of surrounding soft tissues, including ligaments, muscles, and neurovascular structures.

Ligaments, such as the anterior and posterior longitudinal ligaments and ligamentum flavum, appear with low signal intensity on both T1 and T2-weighted images. Muscles surrounding the cervical spine exhibit intermediate signal intensity on both sequences. Neurovascular structures, such as the vertebral arteries and jugular veins, can be identified based on their characteristic location and signal intensity.

Assessing Vertebral Alignment and Spinal Canal Dimensions

Evaluating vertebral alignment and spinal canal dimensions is a critical component of cervical spine MRI interpretation. Normal vertebral alignment is characterized by smooth, continuous curves without any significant subluxation or displacement. The spinal canal should be of adequate size to accommodate the spinal cord without compression.

MRI allows for precise measurement of spinal canal diameter and assessment of any potential narrowing or stenosis. The presence of vertebral malalignment or spinal canal stenosis can indicate underlying pathology, such as spondylolisthesis, disc herniation, or facet joint arthropathy. Careful assessment of these parameters is essential for accurate diagnosis and treatment planning.

Common Cervical Spine Abnormalities: A Guide to MRI Findings

To accurately interpret MRI scans of the cervical spine and identify pathologies, a solid understanding of normal anatomy and its corresponding appearance on MRI is paramount. This foundation is essential for differentiating between normal variations and pathological conditions, ensuring accurate diagnoses and appropriate patient management. This section will navigate the landscape of common cervical spine abnormalities, providing a guide to their characteristic appearances on MRI. We'll explore conditions like disc herniation, spinal stenosis, spondylosis, myelopathy, and radiculopathy, offering insights into their pathophysiology and diagnostic MRI features.

Cervical Disc Herniation

Pathophysiology and Classification

Cervical disc herniation occurs when the nucleus pulposus, the gel-like center of the intervertebral disc, protrudes through a tear in the annulus fibrosus, the tough outer layer. This can result from age-related degeneration, trauma, or repetitive stress. MRI allows for precise classification of disc herniations based on their morphology and extent:

• Disc Bulge: A generalized extension of the disc beyond the vertebral body endplates.

• Disc Protrusion: A focal or asymmetrical extension of the disc, with the base wider than the herniated portion.

• Disc Extrusion: A more pronounced herniation where the herniated fragment is wider than the base connecting it to the disc.

• Sequestration: The herniated fragment has completely separated from the parent disc.

MRI Features and Nerve Root Compression

MRI is highly sensitive for detecting disc herniations and assessing their impact on surrounding neural structures. Key MRI features include:

• Altered Disc Signal Intensity: The herniated disc may exhibit altered signal intensity on T2-weighted images due to dehydration or inflammation.

• Deformation of the Thecal Sac: The herniation can indent or compress the thecal sac, which contains the spinal cord and nerve roots.

• Nerve Root Compression: Direct visualization of nerve root compression is a crucial diagnostic finding. The affected nerve root may appear displaced, flattened, or edematous.

• Spinal Cord Impingement: Large central disc herniations can directly compress the spinal cord, leading to myelopathy.

Cervical Spinal Stenosis

Etiology and Measurement

Cervical spinal stenosis refers to the narrowing of the spinal canal, which can compress the spinal cord and nerve roots. The etiology is often multifactorial, involving:

• Degenerative Changes: Spondylosis, disc herniation, and facet joint arthropathy can all contribute to spinal canal narrowing.

• Congenital Factors: Some individuals have a congenitally narrow spinal canal.

• Ligamentum Flavum Hypertrophy: Thickening of the ligamentum flavum can encroach upon the spinal canal.

MRI plays a vital role in diagnosing and quantifying spinal stenosis.

MRI Criteria and Evaluation

• Spinal Canal Diameter Measurement: The anteroposterior diameter of the spinal canal is measured on sagittal MRI images. A diameter of less than 12 mm generally indicates relative stenosis, while less than 10 mm suggests absolute stenosis.

• Spinal Cord Compression Assessment: MRI allows direct visualization of spinal cord compression. The degree of compression can be graded based on the extent of cord flattening and the presence of cord signal changes.

• Ligamentum Flavum and Facet Joint Evaluation: MRI can assess for ligamentum flavum hypertrophy and facet joint arthropathy, both of which can contribute to spinal stenosis.

Cervical Spondylosis

Pathogenesis and MRI Findings

Cervical spondylosis is a degenerative condition affecting the intervertebral discs and facet joints of the cervical spine. It is a common age-related finding, but can lead to significant symptoms in some individuals. The pathogenesis involves:

• Disc Degeneration: Dehydration and loss of disc height.

• Osteophyte Formation: Bony spurs that form along the vertebral body endplates and facet joints.

MRI findings in spondylosis include:

• Disc Space Narrowing: Reduced height of the intervertebral disc space.

• Endplate Sclerosis: Increased signal intensity on T1-weighted images and decreased signal intensity on T2-weighted images at the vertebral body endplates.

• Vertebral Body Remodeling: Alterations in the shape and contour of the vertebral bodies.

Foraminal Stenosis and Nerve Root Compression

Spondylosis can lead to foraminal stenosis, narrowing of the intervertebral foramina through which the nerve roots exit. This can result in nerve root compression and radicular symptoms. MRI can assess the degree of foraminal stenosis and identify nerve root impingement.

Cervical Myelopathy

Definition, Causes, and MRI Features

Cervical myelopathy refers to spinal cord dysfunction due to compression. The cause is usually spinal stenosis or from an extrinsic source compressing the spinal cord. MRI plays a key role in the diagnostic evaluation and in assessing the severity of the condition. MRI features include:

• Spinal Cord Edema: Increased signal intensity within the spinal cord on T2-weighted images, indicating edema or inflammation.

• Spinal Cord Atrophy: Decreased size of the spinal cord, reflecting chronic compression and neuronal loss.

• Signal Intensity Changes: Altered signal intensity within the spinal cord on T1-weighted and T2-weighted images, which can indicate myelomalacia (softening of the spinal cord).

• Increased T2 Signal Intensity: The most sensitive early finding that is typically associated with myelopathy.

Correlation of MRI Findings with Clinical Symptoms

• The extent and severity of MRI findings correlate with clinical symptoms. The level of spinal cord compression and signal changes on MRI can often be correlated with the patient's neurological deficits.

Cervical Radiculopathy

Pathophysiology and MRI Findings

Cervical radiculopathy refers to nerve root dysfunction. This occurs when the nerve roots are compressed in their course from the spinal cord through the neural foramen. Pathologies include disc herniation, spondylosis, and foraminal stenosis. Key MRI findings include:

• Nerve Root Enhancement: Increased signal intensity on contrast-enhanced images, suggesting inflammation or irritation of the nerve root.

• Nerve Root Enlargement: Enlargement of the nerve root, which can be seen in cases of inflammation or tumor involvement.

• Nerve Root Displacement: Displacement of the nerve root by a disc herniation or osteophyte.

Assessment of Foraminal Stenosis and Disc Herniation

MRI is essential for evaluating the cause of radiculopathy. It can assess the degree of foraminal stenosis and identify disc herniations that are impinging on the nerve roots.

Other Cervical Spine Abnormalities

Cervical Fractures

MRI can be invaluable in evaluating cervical fractures, particularly in cases where conventional radiographs are negative or equivocal.

• Acute Fractures: MRI can detect bone marrow edema and ligamentous injuries associated with acute fractures.

• Chronic Fractures: MRI can assess for nonunion, pseudoarthrosis, and spinal cord compression in chronic fractures.

Cervical Tumors (Benign & Malignant)

MRI is the preferred imaging modality for evaluating cervical tumors.

• MRI Characteristics: The size, location, and signal characteristics of the tumor can be assessed.

• Contrast Enhancement: The pattern of contrast enhancement can help differentiate between benign and malignant tumors. Gadolinium-based contrast agents enhance the visibility of tumors by highlighting areas of increased blood flow or disruption of the blood-brain barrier. This helps characterize lesions and delineate their extent.

MRI Techniques and Protocols for Cervical Spine Imaging

To accurately interpret MRI scans of the cervical spine and identify pathologies, a solid understanding of normal anatomy and its corresponding appearance on MRI is paramount. This foundation is essential for differentiating between normal variations and pathological conditions, ensuring the appropriate application of MRI sequences tailored to specific clinical questions. The effectiveness of cervical spine MRI relies heavily on the selection and optimization of imaging protocols, encompassing both standard and advanced techniques. This section delves into the principles, advantages, and limitations of these techniques.

Standard MRI Sequences

Standard MRI sequences form the cornerstone of cervical spine imaging. These sequences, including T1-weighted, T2-weighted, and STIR, provide complementary information about the different tissue characteristics within the cervical spine. Each sequence relies on distinct MRI parameters to generate contrast, allowing for the differentiation of various anatomical structures and pathological processes.

T1-Weighted Imaging

T1-weighted imaging provides excellent anatomical detail and is particularly useful for visualizing the vertebral bodies, bone marrow, and intervertebral discs. This sequence is sensitive to fat content, with tissues containing fat appearing bright (high signal intensity) and water-containing tissues appearing dark (low signal intensity).

The principles behind T1-weighted imaging involve selecting specific repetition time (TR) and echo time (TE) parameters that maximize the signal difference between tissues with different T1 relaxation times.

Advantages of T1-weighted imaging include its high spatial resolution and its ability to delineate anatomical structures clearly. It is especially useful in identifying fractures, bone marrow lesions, and changes in vertebral alignment.

However, limitations include its relative insensitivity to edema and inflammation, which are better visualized on T2-weighted sequences. Also, it can be less effective in detecting subtle soft tissue abnormalities.

T2-Weighted Imaging

T2-weighted imaging is highly sensitive to fluid and is invaluable in detecting edema, inflammation, and other fluid-containing pathologies within the cervical spine. In this sequence, fluid appears bright (high signal intensity), while tissues with low water content appear dark (low signal intensity).

Similar to T1-weighted imaging, T2-weighted imaging relies on specific TR and TE parameters to optimize contrast based on T2 relaxation times.

The advantages of T2-weighted imaging include its superior ability to visualize spinal cord edema, disc hydration, and inflammatory processes affecting the spinal canal and nerve roots. It is also useful for identifying syringomyelia and other fluid-filled lesions.

However, limitations include lower spatial resolution compared to T1-weighted imaging and potential difficulty in differentiating between various fluid collections. Furthermore, its sensitivity to motion artifacts can sometimes degrade image quality.

STIR Imaging

Short Tau Inversion Recovery (STIR) is a type of T2-weighted sequence that suppresses the signal from fat, further enhancing the conspicuity of fluid and edema. This sequence is particularly useful for detecting subtle bone marrow edema, inflammation, and occult fractures.

The STIR sequence employs an inversion pulse followed by a short delay (TI) to null the signal from fat, thereby increasing the signal intensity of water and edema.

The advantages of STIR imaging include its high sensitivity to edema and inflammation, making it ideal for detecting occult fractures, bone marrow infiltration, and inflammatory lesions. It is also less susceptible to artifacts from metal implants compared to other T2-weighted sequences.

Limitations include lower spatial resolution and potential for artifacts from chemical shift and magnetic susceptibility. Additionally, the lack of fat signal can sometimes make it difficult to delineate anatomical structures clearly.

Advanced MRI Techniques

In addition to the standard MRI sequences, advanced techniques, such as contrast enhancement, can provide valuable diagnostic information in specific clinical scenarios.

Contrast Enhancement (Gadolinium)

Contrast enhancement, typically using gadolinium-based contrast agents, is employed to improve the visualization of vascular structures, inflammatory processes, and neoplastic lesions within the cervical spine. Gadolinium enhances areas with increased vascularity or disruption of the blood-brain barrier, allowing for better characterization of these abnormalities.

Following intravenous administration, gadolinium accumulates in tissues with increased blood flow or compromised barriers, leading to an increase in signal intensity on T1-weighted images.

Indications for contrast enhancement in cervical spine MRI include suspected infection, inflammation, tumor, or post-operative evaluation.

Enhancement patterns can provide important clues about the nature of the underlying pathology, with different types of lesions exhibiting characteristic enhancement patterns.

However, it is essential to be aware of potential adverse reactions to gadolinium-based contrast agents, including allergic reactions and, rarely, nephrogenic systemic fibrosis in patients with severe renal impairment. Careful patient screening and appropriate contrast agent selection are crucial to minimize these risks.

MRI Interpretation and Reporting: A Systematic Approach

[MRI Techniques and Protocols for Cervical Spine Imaging To accurately interpret MRI scans of the cervical spine and identify pathologies, a solid understanding of normal anatomy and its corresponding appearance on MRI is paramount. This foundation is essential for differentiating between normal variations and pathological conditions, ensuring the accurate detection and diagnosis of abnormalities.]

The interpretation of cervical spine MRI requires a systematic approach to ensure thorough evaluation and accurate reporting. A structured methodology minimizes the risk of overlooking subtle but significant findings and promotes consistency in interpretation across different radiologists.

This section outlines a strategic framework for analyzing cervical spine MRI images and generating comprehensive reports, essential for informed clinical decision-making.

Systematic Approach to Image Interpretation

A systematic approach to image interpretation is the cornerstone of accurate MRI reading. This entails a step-by-step evaluation of the cervical spine, ensuring that each anatomical structure is meticulously assessed.

This section details methods for evaluating vertebral alignment, disc height, spinal canal dimensions, neural foramina, assessing spinal cord signal intensity, compression, edema, and identifying/characterizing nerve root abnormalities.

Evaluating Vertebral Alignment, Disc Height, and Spinal Canal Dimensions

The initial step involves assessing vertebral alignment, ensuring that the vertebrae are properly aligned in the sagittal plane. Subtle misalignments can indicate instability or underlying ligamentous injury.

Next, disc height should be evaluated at each level, looking for narrowing that may suggest degeneration or disc desiccation. Furthermore, the dimensions of the spinal canal are crucial. Measure the anteroposterior diameter to identify spinal stenosis, which can lead to spinal cord compression.

Assessing Neural Foramina

The neural foramina, through which nerve roots exit, should be scrutinized for narrowing or impingement. This is best assessed on oblique or axial images, looking for signs of foraminal stenosis caused by osteophytes, disc herniation, or facet joint hypertrophy.

Assessing Spinal Cord Signal Intensity, Compression, and Edema

Evaluation of the spinal cord involves assessing its signal intensity on T1- and T2-weighted images. Abnormal signal intensity, such as hyperintensity on T2-weighted images, may indicate edema, inflammation, or myelomalacia.

Carefully assess for spinal cord compression, noting the degree and location of the compression, as well as any associated changes in cord morphology. Edema within the spinal cord can be a sign of acute compression or myelopathy.

Identifying and Characterizing Nerve Root Abnormalities

Carefully examine the nerve roots for any signs of abnormality, such as enlargement, displacement, or abnormal enhancement on post-contrast images. Nerve root impingement by disc herniations or osteophytes should be documented, noting the specific nerve root affected.

Structured Reporting of MRI Findings

The final product of image interpretation is the MRI report, a vital communication tool between the radiologist and referring clinician. A structured, detailed, and clear report is critical for informing diagnosis and treatment strategies.

Essential Components of an MRI Report

An MRI report should include several essential components.

• Begin with the patient's demographics and the date of the study.
• List the indications for the MRI, providing context for the findings.
• Describe the imaging protocol used, including sequences and any contrast administration.
• Present the findings in a structured manner, starting from the cervical spine and its alignment.
• Include the details on disc height, spinal canal dimensions, neural foramina, spinal cord, and nerve roots.
• Provide a clear and concise summary of the findings and an impression.
• Offer differential diagnoses as needed, and suggest further evaluation or correlation with clinical findings.

Recommendations for Correlating MRI Findings with Clinical Symptoms

While MRI provides valuable anatomical information, it is crucial to correlate the imaging findings with the patient's clinical symptoms. The radiologist should consider the patient's history, physical examination findings, and any relevant laboratory results when interpreting the MRI.

• Report any discrepancies between the imaging findings and clinical presentation. For example, significant disc herniation on MRI may be asymptomatic in some patients, while subtle findings may correlate with severe symptoms in others.
• Suggest further investigation or consultation with specialists (e.g., neurologist, spine surgeon) if needed to clarify the clinical significance of the MRI findings.

Ultimately, a well-structured MRI report that integrates imaging findings with clinical context ensures that the clinician has the information needed to make informed decisions about patient care.

The Multidisciplinary Team: Collaborative Roles in Cervical Spine Abnormality Management
