Which imaging modality is most sensitive for detecting acute spinal cord injury?

• A. MRI
• B. CT
• C. Doppler ultrasound
• D. X-ray

Answer: (A)

In acute spinal cord injury, the most sensitive tool is MRI because it shows soft-tissue changes inside and around the cord that other imaging routinely misses. MRI reveals spinal cord edema, contusions, and hemorrhage, which can appear hours after injury and before bone damage becomes evident. It also assesses ligaments, discs, and the space available for the cord, helping identify canal compromise and hidden injuries. CT and X-ray are excellent for bone injuries and alignment but miss early cord pathology and soft-tissue damage. Doppler ultrasound isn’t used for evaluating the spinal canal. So, MRI’s ability to visualize soft-tissue and cord changes makes it the best choice for detecting acute spinal cord injury.
