[Cranial MRI in hepatic disease--relationship between MR imaging and clinical symptoms and laboratory analysis of liver function].
Magnetic resonance imaging studies on 12 cases with hepatic disease were performed. In 11 adult patients with chronic hepatic failure, T1-weighted images demonstrated increased signal in the globus pallidus in 7 patients (63.6%) and in some parts of the cerebral peduncles in 6 patients (54.5%), in the substantia innominata in 4 patients (36.3%). There might be some correlation between the abnormality of MR imaging and clinical symptoms of hepatic encephalopathy. There was a significant correlation between the intensity of the signal and Fischer's ratio of amino acid analysis. In one patient with Wilson's disease, who developed symptoms of central nervous system, T1-weighted images demonstrated increased signal in the globus pallidus. After treatment of D-penicillamine, the signal of the globus pallidus decreased.
