Abstract:
The value of computed tomography in the diagnosis of multiple sclerosis is undisputed. The examination is usually carried out as a routine part of the examination program. We report on the CT results of 112 patients with confirmed or suspected MS. Seventy-three patients were examined without, 39 with intravenous administration of a contrast medium. In 41% of the patients, isolated or multiple hypodense foci were found as a manifestation of a multilocular demyelinization process. In 17.8%, only cerebro-atrophic changes were encountered. In 30.3% of the cases the CT showed normal results. In the group of patients examined with a contrast medium, a pathological contrast medium concentration was found in 30.7%. The differential diagnostic demarcation against other diseases of the CNS with similar CT findings and problems of differential diagnosis with MRI are discussed.
