Computer-assisted myelography in degenerative abnormalities of the cervical vertebral column.

ABSTRACT

In 19 patients with symptoms suggestive of a cervicobrachial syndrome due to degernative lesions of the cervical spine, a CT scan was made after intrathecal administration of metrizamide. The images thus obtained supply adequate information on the extent of bone apposition, if any, on the degree of displacement and compression of the spinal cord, and on the condition of the intervertebral foramina. A CT scan is indicated in the case of discrepancy between myelographic findings and clinical diagnosis. In the case of recurrent postoperative symptoms, too, CT scans have proved to supply valuable information.
