In a hemodynamically stable patient with suspected spine injury, under what circumstances is MRI considered?

• A. If neurological deficits persist or soft tissue injury is suspected.
• B. MRI is the first-line imaging for all spine injuries.
• C. MRI is never used in spine injury assessment.
• D. MRI should be avoided if CT shows stable findings.

Answer: (A)

In a hemodynamically stable patient with suspected spine injury, MRI is used when there are persistent neurological deficits or when soft-tissue injury is suspected. CT is excellent for visualizing bone and is usually the initial imaging in trauma, but MRI provides detailed information about the spinal cord, ligaments, discs, and potential epidural hematomas. This helps determine if there is ongoing neural compromise or ligamentous disruption that would change management, such as needing decompression or stabilization. If CT shows no fracture and there are no neuro deficits, MRI may not be necessary. The other options aren’t correct because MRI isn’t the universal first-line test, it’s not never used, and it shouldn’t be avoided solely based on CT stability if clinical signs point to soft-tissue or neural injury.
