Structured Reporting — Spine MRI¶
Overview¶
Structured reporting ensures consistent, comprehensive evaluation of spine MRI and clear communication with referring clinicians. This article provides a template framework for spine MRI reports.
Cervical Spine MRI Template¶
Clinical Information: [Indication, symptoms, relevant history]
Technique: [Sequences, planes, contrast administration]
Alignment: Cervical lordosis (maintained/straightened/reversed). Listhesis (present/absent at each level).
Vertebral Bodies: Marrow signal (normal/abnormal). Compression fractures (present/absent). Hemangiomas. Endplate changes (Modic type).
Intervertebral Discs: At each level (C2-3 through C7-T1): disc height, signal, herniation (protrusion/extrusion, central/paracentral/foraminal, laterality), effacement of the cord or nerve roots.
Spinal Canal: Central canal diameter and any stenosis (mild/moderate/severe). Cord signal (normal/abnormal — T2 hyperintensity suggesting myelopathy).
Neural Foramina: Each level bilaterally — stenosis (none/mild/moderate/severe), nerve root compression.
Spinal Cord: Caliber (normal/atrophic/expanded). Signal (normal/abnormal). Syrinx.
Posterior Elements: Facet joints, ligamentum flavum, interspinous ligaments.
Paravertebral Soft Tissues: Normal or abnormal.
Lumbar Spine MRI Template¶
Similar structure but adapted for the lumbar spine:
Conus Medullaris: Position (normal at L1-L2 or below). Signal.
Cauda Equina: Normal or abnormal (clumping, enhancement, mass).
Intervertebral Discs: At each level (L1-2 through L5-S1): disc height, signal, annular fissure, herniation (protrusion/extrusion/sequestration, central/paracentral/foraminal/far lateral), nerve root compression.
Central Canal: Stenosis grading at each level.
Lateral Recesses: Stenosis bilaterally at each level.
Neural Foramina: Stenosis bilaterally at each level.
Clinical Pearl
A structured report should answer the referring clinician's specific question first, then provide the systematic evaluation. If the question is "L4-5 disc herniation?" — answer that directly in the impression before listing all other findings. Structured reporting improves completeness but should never come at the expense of clear, direct communication.
Key Points¶
- Structured reports improve consistency and reduce omissions
- Always address the clinical question directly
- Grade stenosis consistently (mild/moderate/severe)
- Report cord signal changes explicitly — T2 hyperintensity = myelopathy until proven otherwise
- Include all levels, even if normal — "no stenosis at L1-2" is clinically useful information
