Structured Reporting — Spine CT¶
Overview¶
Spine CT structured reporting focuses on bony anatomy, alignment, hardware (if present), and canal dimensions. CT provides superior bone detail compared to MRI but limited soft tissue evaluation.
Cervical Spine CT Template (Trauma)¶
Clinical Information: [Mechanism, neurological status]
Alignment: Lordosis. Listhesis. Widening of interspinous or interlaminar distance. Facet joint alignment.
Vertebral Bodies: Fractures (type, level, degree of compression, retropulsion). Vertebral body height. Endplate integrity.
Posterior Elements: Pedicle fractures. Lamina fractures. Spinous process fractures. Facet fractures or dislocations (unilateral/bilateral). Lateral mass fractures.
Disc Spaces: Height (normal/narrowed). Vacuum phenomenon.
Spinal Canal: AP diameter. Canal compromise from fracture fragments or disc material.
Neural Foramina: Patency. Bony foraminal stenosis.
Craniocervical Junction: Occipital condyles. Atlas (C1) integrity. Odontoid (C2). ADI. Atlantoaxial alignment.
Soft Tissues: Prevertebral soft tissue swelling (suggestive of ligamentous injury or hemorrhage in trauma). Paravertebral hematoma.
Post-Surgical Spine CT Template¶
Hardware: Type, position, integrity. Screw trajectory (medial/lateral breach). Lucency around screws. Rod integrity. Cage position.
Fusion Status: Bridging bone (present/absent). Graft incorporation. Pseudarthrosis.
Adjacent Levels: Degeneration at levels above and below the construct.
Clinical Pearl
In trauma CT, always report prevertebral soft tissue thickness — abnormal swelling (>7 mm at C2, >14 mm at C6 on lateral) may be the only clue to an occult ligamentous injury, even when the bones appear normal. This finding should prompt MRI for further evaluation.
Key Points¶
- CT is the primary modality for trauma evaluation and hardware assessment
- Report every posterior element individually in trauma (pedicles, laminae, facets, spinous processes)
- Prevertebral soft tissue swelling in trauma suggests occult ligamentous injury
- Post-surgical CT must evaluate hardware position, integrity, and fusion status
- Sagittal and coronal reformats are essential — do not rely on axial images alone
