title: MRI in schizophrenia: basal ganglia and white matter T1 times.
abstract: The T1 relaxation time of the basal ganglia (putamen, globus pallidus and head of caudate) and of the frontoparietal centrum semiovale was compared between 49 schizophrenic patients and 36 healthy controls. Previous reports of increased T1 time in the basal ganglia were not confirmed, and group differences were not detected within the white matter. Within patients T1 values could not be related to tardive dyskinesia or other clinical features. Normal variation seen in basal ganglia T1 times is described for the first time: lowest values occur in the globus pallidus and highest in the caudate, and values within the putamen increase rostrally.
