Efficacy of respiratory-triggered fast spin echo MR cholangiopancreatography on intermediate MR imaging

MR cholangiopancreatography (MRCP) using a respiratory-triggered fast spin-echo technique was performed on intermediate MR imaging in 26 patients with suspected biliary disease. In almost all of 12 patients without dilated biliary tract, the hilum of the liver and extrahepatic bile duct were clearly visualized. All of 11 cases of cholelithiasis were demonstrated. In all 4 cases of obstructive jaundice, dilatation and obstruction of the bile ducts were clearly demonstrated. Respiratory-triggered fast spin-echo MRCP is a non-invasive technique for visualization of the biliary tract and biliary disease on intermediate MR imaging.
