Thirty-three patients with either primary spinal cord tumors (n = 18), intradural tumors excavating into the cord (n = 9), or spinal arteriovenous malformations (AVM) (n = 6) were studied with magnetic resonance (MR) imaging. In 25 of 38 examinations (66%) (five patients were studied twice), MR provided more information than that provided by other neuroradiologic procedures. In several cases, MR affected patient management decisions. Advantages of MR, in addition to the absence of ionizing radiation and its noninvasive nature, include good spinal cord-CSF-theca contrast, lack of bone-derived artifacts, ease of multiplanar imaging, improved discrimination between intra- and extramedullary lesions, better definition of tumoral cavities and possible distinction from true syringes, ability to help one recognize thrombus formation within an AVM, and ease of follow-up of cord lesions for possible size changes. Apart from factors precluding the study in several patients (life support systems, pacemakers, claustrophobia, neurovascular clips), disadvantages of MR imaging include motion artifacts (prevalent in thoracolumbar area), poor capability of typing and grading of tumors, potential of false-positive results, poor detection of calcification, and poor delineation of feeders and drainers of AVM.
