DIAGNOSIS OF SPINAL ARTERIOVENOUS-MALFORMATIONS BY MRI AT 1.0 T

Eight patients were examined by magnetic resonance imaging (MRI) at 1. 0 T; seven had an angiographically proved spinal intradural arterioven ous malformation and one had a hemangioblastoma of the spinal cord. My elography was also performed in five and computed tomography (CT) in f our patients. The clinical and radiological findings are presented, MR I revealed the location and extent of the lesion, Myelomalacia, edema, and hematomyelia were demonstrated in three patients. In our opinion MRI is the method of choice for the diagnosis of spinal arteriovenous malformation and facilitates spinal angiography, whereas myelography a nd CT do not provide any further information.
