Magnetic Resonance Imaging in Psychiatry*

Abstract

Magnetic resonance imaging (MRI) is a relatively new radiological technique that may be useful in the study of psychiatric illness. MRI gives detailed structural information about the brain and also allows quantification of functional change. Current areas of study relevant to psychiatry include: schizophrenia, dementia, epilepsy and, to a lesser extent, alcohol and affective disorders. The authors review the basic principles of MRI, discuss the recent application to psychiatry, indicate its potential advantages and comment on the current limitations of this imaging modality.
