T2 hyperintense foci on magnetic resonance images of schizophrenic patients and controls.
High resolution magnetic resonance imaging (MRI) of the brain was performed on 18 male schizophrenic patients and 15 male normal control subjects using an identical imaging protocol. The number and size of T2 hyperintense foci were clinically quantified by an academic radiologist. Large foci (greater than or equal to 3 mm in diameter) were observed more frequently on patient images (7/18) than on control images (1/15). The imaging protocol detected high rates of focal hyperintensities, but no differences between patients and controls were noted in the total affected brain area (sum of focal areas) or in the presence or absence of foci.
