Cholestasis results from failure to clear bile from the liver into the duodenum. Prolonged cholestasis results in accumulation of bile salts and hepatocellular damage. Phosphatidylcholine and glycine/taurine conjugated bile acids may play a role in the pathophysiology of cholestasis. Primary Scelerosing Cholangitis (PSC) is a chronic cholestatic liver disorder with inflammation, narrowing and finally obstruction of bile ducts. Considering the success of in vivo 1-H MRS in detecting human bile components, we are comparing in this study 1-D and 2-D spectra of human bile in healthy volunteers and PSC patients obtained using a 3T clinical scanner and our home-built receive array coil.
