[Contribution to proton nuclear magnetic resonance imaging in multiple sclerosis. Contribution of a multiple spin...

Single or multiple parenchymatous anomalies were detected in 48 of 49 patients with multiple sclerosis by proton magnetic resonance imaging (MRI) combined with a spin-echo sequence in the 4 planes of the section passing through the ventricular bodies. Lesions were identified in the frontal, orbital and particularly juxta-ventricular white substance, and were of variable appearance, the most common being spots in the parenchyma and juxta-ventricular bands. A limited number of sections is sufficient for the MRI study of anomalies in clinically defined multiple sclerosis, the diagnostic value of this examination suggested by these findings requiring confirmation by prospective studies.
