Spine MRI: A Review of Commonly Encountered Emergent Conditions

Area of Science:

• Radiology
• Emergency Medicine
• Neurosurgery

Background:

• Magnetic resonance imaging (MRI) utilization has surged due to increased availability and faster acquisition.
• MRI is frequently employed in emergent settings, offering crucial diagnostic information beyond other modalities.
• Acute spine pathology requires timely and accurate diagnosis, often necessitating advanced imaging.

Purpose of the Study:

• To provide updated indications for spine MRI in the emergency department (ED).
• To review MRI appearances of common acute spine pathologies.
• To highlight MRI's unique diagnostic capabilities for spinal conditions.

Main Methods:

• Review of current literature and clinical guidelines for spine MRI in the ED.
• Analysis of imaging characteristics for various acute spinal pathologies.
• Focus on conditions where MRI offers superior diagnostic yield compared to other modalities.

Main Results:

• Established up-to-date indications for emergent spine MRI.
• Detailed MRI findings for traumatic injuries, myelopathy, infection, neoplasia, degenerative disc disease, and postoperative complications.
• Emphasized the role of MRI in diagnosing conditions not clearly visualized by other imaging techniques.

Conclusions:

• Spine MRI is a critical tool in the ED for diagnosing a spectrum of acute pathologies.
• Understanding specific MRI appearances aids in rapid and accurate diagnosis of emergent spinal conditions.
• MRI provides essential diagnostic information for complex spine cases presenting acutely.
