INTRODUCTION
Magnetic resonance (MR) is the imaging modality of choice for the evaluation of most suspected central nervous system (CNS) pathology. It is less clear, however, when MR imaging (MRI) should be performed on an emergent basis. The timing of emergent MRI has significant implications with respect to patient care, equipment availability, necessary hardware and software, and staffing considerations. Therefore, it is important to identify those clinical situations for which emergent MRI evaluation is required.
The most common indication for emergent MRI is suspected spinal cord compression (SCC)1-2 as MRI is a safer and a more detailed examination than myelography followed by computed tomography (CT). Other indications for emergent CNS MRI include evaluation for suspected dural venous sinus thrombosis (DVST)3 or suspected arterial dissection,4 as MRI is safer and less expensive than conventional endovascular angiography and is often as diagnostic. Additional relative indications for emergent MRI evaluation . . . [Full Text of this Article]
