Neuroimaging in infections and demyelinating disease.

Computerized tomography and magnetic resonance imaging continue to illuminate the changes that occur in the central nervous system in infections and demyelinating disease. Imaging in the acquired immune deficiency syndrome helps to better understand neurological complications. Magnetic resonance imaging also helps to be specific about the diagnosis of cryptococcal meningitis and toxoplasmosis. Major contributions have been made to the understanding of the diagnosis and the living pathology of multiple sclerosis. Experimental studies have identified the mechanism of blood-brain barrier disruption in inflammatory disease.
