MR myelography: imaging findings

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