Clinical Correlation of Neuropsychological Tests With1 H Magnetic Resonance Spectroscopy in Hepatic Encephalopathy

Abstract

1H MRS studies showed changes in regional cerebral biochemistry associated with all grades of HE. There was a reduction in mI/Cr and a reduction in Cho/Cr in patients with low grade and subclinical forms of HE compared with normal subjects. The reduction in mI correlated well with abnormalities observed in neuropsychological tests. Liver transplantation was not associated with significant improvement in these variables.
