Abstract
- A prospective study was deviced to determine the correlation between myelography and computed tomography(CT) in the evaluation of abnormalities of the lumbar intervertebral disk. We compared 12 operated cases, all of whom had both myelogram(either pantopaque or metrizamide) and lumbar computed tomogram preoperatively. On comparison of 15 operated interspace levels of the 12 cases, 15 CT and 12 myelographic diagnoses agreed with the operative diagnoses. A false negative diagnosis and a false positive diagnosis of herniated nucleus pulposus, and a false negative diagnosis of lateral recess stenosis were made on myelography. In addition to demonstrates lumbar disk disease as effectively as myelography, high-resolution CT also reveals the facet joints and cross-sectional area of the spinal canal and eliminate the invasive diagnostic procedure that involves risk.
