A magnetic resonance imaging (MRI) study of 20 chronic schizophrenic outpatients (5 women and 15 men) and 20 healthy volunteers, individually matched for age and sex, was conducted. Schizophrenics showed a statistically significant lateral ventricular enlargement and smaller corpus callosum: brain ratio than controls. There were no statistically significant differences in hemispheric measurements between groups. Nevertheless, we found a wider right frontal width versus the left in the patient group but not in the control group, and more frontal protuberances in the right hemisphere in the patient group. Possible meanings and implications of these findings for a pathophysiological hypothesis are discussed.

D008279 Magnetic Resonance Imaging Non-invasive method of demonstrating internal anatomy based on the principle that atomic nuclei in a strong magnetic field absorb pulses of radiofrequency energy and emit them as radiowaves which can be reconstructed into computerized images. The concept includes proton spin tomographic techniques.
