Interprétation d'un hypersignal T1 spontané intracrânien : revue iconographique

Correct interpretation of high intensity intracranial T1 signals, found in several situations, is a difficult challenge for the radiologist. Optimal conditions, sometimes requiring complementary sequences or other imaging techniques, are required for adequate diagnosis. Using a large set of illustrations, we examine the physical basis of these spontaneous high intensity signals on T1-weighted images.
