MR imaging of the spine: Urgent and emergent indications

Spinal emergencies and urgent conditions must be recognized early so that the diagnosis can be quickly confirmed and treatment can be instituted to possibly prevent permanent loss of function. The American College of Radiology provides guidelines for recognition of patients presenting with myelopathy or acute low back pain who require further evaluation for suspicion of more serious problems and contribute to appropriate imaging utilization. Spinal emergencies include spinal cord compression secondary to vertebral fracture or space occupying lesion, spinal infection or abscess, vascular or hematologic damage, severe disc herniation, and spinal stenosis.
