  • Title: Computerized tomography in the diagnostic evaluation of multiple sclerosis.
    Author: Hershey LA, Gado MH, Trotter JL.
    Journal: Ann Neurol; 1979 Jan; 5(1):32-9. PubMed ID: 311613.
    Abstract:
    Sixty-six patients with a tentative or certain diagnosis of multiple sclerosis (MS) were examined with cranial computerized tomography (CT). Abnormalities found in 19 (29%) included discrete areas of decreased white matter density, enlarged ventricles, cortical atrophy, and focal areas of contrast enhancement. The presence of white matter lucencies and ventricular dilatation correlated with an increased incidence of diffuse hyperreflexia and mental impairment. Since half the patients with contrast-enhancing lesions were clinically stable, their lesions may represent acute asymptomatic plaques. Abnormalities on CT scan were observed more often in older patients whose disease had lasted longer and was clinically more definite. Since findings were sparse in early, less definite disease, the use of CT as a purely diagnostic tool is limited.
