Importance of computer-assisted myelography in diseases affecting the vertebral column.

Of a series of 20 patients in whom CT scans revealed lesions of the vertebral column, 6 cases are discussed which confirm the efficacy of this method of investigation. Good information is obtained in particular on pathological processes in which optimally exact localization is required preoperatively and in tumor relapses. CT scanning is also indicated when myelography proves to be impossible, e.g., due to adhesions. Computer-assisted myelography, however, does not yet seem suitable to be used as a routine procedure.
