Cerebral Oxygen, Blood Flow and Ammonia Uptake in Patients With Cirrhosis and an Acute Episode of Hepatic Encephalopathy (HE)
The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government.
Read our disclaimer for details.
We wish to study patients with liver cirrhosis during and 2 weeks after an acute episode of liver coma (hepatic encephalopathy). By means of Positron Emission Tomography we investigate; brain blood flow, brain ammonia uptake and brain oxygen consumption. We hypothesize that blood flow an oxygen consumption is diminished and ammonia uptake increased during an acute episode of hepatic encephalopathy.
