Pernasal catheter perfusion with MTBE and subsequent endoscopic lithotripsy is an effective treatment of complicated common bile duct lithiasis in which a first endoscopic attempt has failed. The authors analyzed their experience in 1990.
Biliary enhanced MRI (BEMRI) by Gd-DTPA via PTCD and/or PTGBD tube for obstructive jaundice was performed in 8 patients. In all cases, biliary tract was clearly visualised as high signal intensity on T1 weighted images. On same images, primary lesion such as common bile duct cancer was also visualised as well as portal system. In addition, MR angiography (MRA) by 2D-time of flight method was performed. MRA with BEMRI shows portal encasement on the same image as biliary tract obstruction. It suggests MRA with BEMRI may replace the other modality for obstructive jaundice.
