We present results showing that brain metabolite T2 relaxation times, long assumed to be relatively constant in MRS based studies of neuropsychiatric disorders, are in fact significantly different in bipolar and schizophrenic subjects compared with healthy controls. These metabolite T2 relaxation measurements may serve as a useful probe to help characterize the cellular microenvironment in these disorders.
