In vivo investigation of white matter pathology in schizophrenia with magnetisation transfer imaging

Abstract

OBJECTIVES This study is the first to use magnetisation transfer imaging (MTI), a technique sensitive to myelin and axonal abnormalities, to investigate the white matter in vivo in patients with schizophrenia. METHODS MTI was performed in 25 schizophrenic patients and 30 healthy controls. A region of interest (ROI) approach was used to obtain magnetisation transfer ratios (MTRs) in several regions of cerebral white matter. RESULTS MTR values were significantly reduced in the right and left temporal regions in schizophrenic patients compared with controls (pCONCLUSIONS Subtle white matter pathology, most likely related to myelin and axonal abnormalities, can be detected in the temporal lobes in schizophrenic patients. MTI may be a useful tool in investigating the white matter in schizophrenia.
