Answer

Answer

Computed tomography (CT) and magnetic resonance imaging (MRI) studies of the brain may be important in ruling out intracranial lesions when the diagnosis of hepatic encephalopathy is in question. [35] MRI has the additional advantage of being able to demonstrate hyperintensity of the globus pallidus on T1-weighted images, a finding that is commonly described in hepatic encephalopathy. [36, 37] This finding may correlate with increased manganese deposition in this portion of the brain.
