MRI Cervical Spine Without Contrast — Dictation, Appropriateness, and Dose for Residents

1. The Mid-Day Stat Read: Myelopathy on the Line

The ED calls. You have a 55-year-old with new-onset gait disturbance, hyperreflexia, and a positive Hoffmann sign. The neurosurgery team is already following the patient and waiting on your read of the stat non-contrast cervical spine MRI. They have one question: is there cord compression with signal change? This isn’t a subtle finding you can circle back to; it’s a potential surgical emergency. Your attending expects a precise, level-by-level description of stenosis and a definitive call on myelomalacia. When I was a resident, this was the kind of case where you double- and triple-check every axial slice, making sure you don’t miss that faint T2 hyperintensity in the cord that changes everything. This guide is built for that moment, providing a structured template and the key principles to nail the read. For more tools like this, check out the residents and fellows resource hub.

2. What an MRI Cervical Spine Without Contrast Covers and What Attendings Look For

An MRI of the cervical spine without contrast is the workhorse for evaluating the spinal cord, nerve roots, and intervertebral discs. It’s the definitive study for radiculopathy and myelopathy. While a CT is superior for acute trauma and bony detail, MRI provides unparalleled soft tissue contrast to directly visualize neural structures.

Your attending will expect a systematic evaluation covering these key areas:

• Alignment: Is there spondylolisthesis or kyphosis/lordosis abnormality?
• Vertebral Bodies: Check marrow signal for metastatic disease or infection, and evaluate for endplate changes (Modic changes) and osteophytes.
• Spinal Cord: Assess for abnormal T2 signal (myelomalacia, edema, MS plaque, syrinx), compression, or atrophy.
• Intervertebral Discs: Describe disc height loss, desiccation, and any herniations (protrusion, extrusion, sequestration) level by level.
• Central Canal and Foramina: Systematically grade the degree of central canal stenosis and neural foraminal narrowing at each level, specifying the cause (e.g., disc-osteophyte complex, ligamentum flavum hypertrophy).
• Incidental Findings: Don’t forget to check the visualized posterior fossa, craniocervical junction, and paraspinal soft tissues.

The core clinical questions this study answers are the presence and severity of cervical disc herniation, central canal stenosis, cord compression with myelomalacia, and intrinsic cord pathologies like multiple sclerosis or transverse myelitis.

3. Radiology Report Template for MRI Cervical Spine Without Contrast

This template provides a solid foundation for your dictation. Modify it with the specific positive findings from your case. The key is a systematic, level-by-level approach that leaves no question unanswered.

Technique

Multiplanar, multisequence MRI of the cervical spine was performed without intravenous contrast. Sequences include sagittal T1, T2, and STIR, as well as axial T1, T2, and T2*-gradient echo images from the craniocervical junction through the upper thoracic spine.

Findings

Alignment: Normal cervical lordosis is [maintained/lost/reversed]. No evidence of anterolisthesis or retrolisthesis.

Vertebral Bodies: Vertebral body heights are maintained. Marrow signal is [normal for age/demonstrates diffuse heterogeneity/shows focal abnormality at C#]. Endplate degenerative changes are noted at [levels].

Spinal Cord: The visualized spinal cord is normal in caliber. There is [no] intrinsic abnormal T2 signal to suggest myelomalacia, edema, or demyelination. The conus medullaris is normally positioned.

Craniocervical Junction: The craniocervical junction is unremarkable. The cerebellar tonsils are in normal position.

Level-by-Level Analysis:
C2-C3: The central canal and neural foramina are patent.
C3-C4: [Describe disc status, central canal stenosis, and foraminal narrowing].
C4-C5: [Describe disc status, central canal stenosis, and foraminal narrowing].
C5-C6: [Describe disc status, central canal stenosis, and foraminal narrowing].
C6-C7: [Describe disc status, central canal stenosis, and foraminal narrowing].
C7-T1: [Describe disc status, central canal stenosis, and foraminal narrowing].

Paraspinal Tissues: The visualized paraspinal soft tissues are unremarkable.

Impression

1. Multilevel degenerative disc disease of the cervical spine, most pronounced at [level(s)], as detailed above.
2. [Mild/Moderate/Severe] central canal stenosis at [level(s)] due to [e.g., disc-osteophyte complex and ligamentum flavum hypertrophy].
3. [Mild/Moderate/Severe] [right/left] neural foraminal narrowing at [level(s)].
4. No evidence of cord compression or abnormal cord signal to suggest myelomalacia.

4. Free Template Sources from the Community

Building a personal macro library is a rite of passage in residency. If you’re looking for more templates to adapt, two great free repositories exist. The Radiological Society of North America (RSNA) curates a comprehensive library at RadReport.org, covering nearly every modality and subspecialty. Another excellent, independently maintained resource is Radiology Templates, based in Australia, which offers a clean interface and well-structured templates.

5. The Next-Level Move: Free-Form Dictation to Structured Report

The challenge with templates is that positive findings force you to stop, edit, and manually structure your sentences. This breaks your flow and slows you down. An alternative approach is to dictate your positive findings in free form—”large left paracentral disc extrusion at C5-C6 causing severe central canal stenosis and cord compression with T2 signal change”—and let an AI tool handle the rest. GigHz Precision AI is designed for this workflow. It takes your natural language dictation of findings and automatically generates a clean, structured report using pre-loaded templates from the American College of Radiology (ACR) and Society of Interventional Radiology (SIR). This approach helps streamline the reporting process, allowing you to focus on the images rather than the dictation system’s quirks.

6. When Should You Order an MRI Cervical Spine Without Contrast? ACR Appropriateness Criteria

The American College of Radiology (ACR) provides evidence-based guidelines on imaging appropriateness. For a non-contrast cervical spine MRI, the key indications fall under myelopathy, radiculopathy, and post-traumatic evaluation.

Per the ACR Appropriateness Criteria for Myelopathy, an MRI of the cervical spine is rated “Usually Appropriate.” This is the primary imaging modality for evaluating for cord compression or intrinsic cord pathology causing symptoms like gait instability or hyperreflexia.

For an adult with acute or increasing cervical pain with radiculopathy but no trauma or red flags, an MRI C-spine without contrast is also “Usually Appropriate.” However, for mechanical neck pain *without* radiculopathy or red flags, imaging is “Usually Not Appropriate” as a first step; conservative management is recommended first.

In the setting of acute spinal trauma, CT is the first-line modality to evaluate for fracture. However, if there is a suspected or confirmed ligamentous, spinal cord, or nerve root injury (often with a neurologic deficit), a follow-up MRI C-spine is “Usually Appropriate” to directly visualize the soft tissues and spinal cord. The same applies to an obtunded trauma patient with a negative CT who cannot be fully assessed clinically.

Alternatives include an MRI with and without contrast if there is suspicion for tumor, infection, or active demyelination. When MRI is contraindicated, a CT or CT myelogram can be considered to evaluate the bony structures and spinal canal, respectively.

7. MRI Cervical Spine Without Contrast Imaging Protocol — Sequences, Parameters, and Pitfalls

A standard non-contrast cervical spine MRI protocol is designed to provide high-resolution anatomical detail of the cord, nerve roots, discs, and marrow. The scan typically takes 20-25 minutes. Key sequences are optimized to highlight specific pathologies, from cord edema on STIR to foraminal fat on T1.

The table below outlines a typical protocol. Note that 3D high-resolution sequences like FIESTA/CISS are increasingly added for sub-millimeter detail of the nerve roots, especially when brachial plexus injury or drop metastases are a concern.

Common protocol pitfalls: Motion artifact from swallowing is a frequent issue; anterior saturation bands are critical to mitigate this. In patients with prior surgery and hardware, standard sequences will be degraded by susceptibility artifact. In these cases, dedicated metal artifact reduction sequences (MAVRIC, MARS, or SEMAC) are necessary to produce diagnostic images.
