MR MYELOGRAPHY - IMAGING FINDINGS

MR myelography, heavily T2-weighted fast spin-echo imaging with fat su ppression, enhances the signal intensity of CSF with subtraction of th e surrounding background signal. Krudy [1], who first described the te chnique, used multiple projections per examination. We illustrate the findings in 80 patients who were examined with a modified MR imaging t echnique that provides increased spatial resolution and uses a single coronal sequence after the conventional MR study. This report illustra tes the usefulness of MR myelography in cases of spinal stenosis or sp inal block, in both the lumbar and thoracic regions.
