In a hemodynamically stable patient with suspected spine injury, what imaging modality is typically used for assessment?

• A. MRI
• B. Plain X-ray
• C. CT scan of the spine
• D. Ultrasound

Answer: (C)

In a stable trauma patient with suspected spine injury, a CT scan of the spine is the imaging study of choice because it rapidly provides detailed, cross-sectional views that accurately detect fractures, dislocations, and canal compromise across the entire spine. This makes it superior to plain X-ray, which can miss subtle injuries and requires multiple views, and to MRI, which is excellent for soft tissue and cord injuries but is slower, less available emergently, and not the initial study used for acute bony assessment. MRI is typically reserved for when neurological deficits are present or when CT findings are inconclusive and there is still suspicion of ligamentous injury or spinal cord injury. Ultrasound offers no useful information for spine assessment.
