Abstract
Purpose: Evaluation of utility and value of a selective projection tec hnique for bile and pancreatic ducts in MRI. Material and methods: 200 patient examinations of the pancreaticobiliary duct system using a tu rbo-SE pulse sequence in ''single-shot'' technique were evaluated in r etrospect concerning anatomic display and diagnostic accuracy compared to surgery, ERCP, i.v. cholangiography, ultrasound and clinical cours e. Results: Non-dilated ducts allowed visualisation of gallbladders in 78%, common bile ducts in 97%, cystic ducts in 80%, intrahepatic main ducts in 71% and pancreatic main ducts in 69%. When dilatation was pr esent, all common bile, intrahepatic main and pancreatic ducts were vi sible. Display of cystic ducts and gallbladders with a detection rate of 69 and 85%, respectively, did not improve. Sensitivities for diagno sing papillary stenoses (n = 6), pancreatic ductal stenoses and dilata tion (n = 13), compressions and dilatations of the biliary tree (n = 3 3) as well as for one choledochal cyst were 100%. Choledudolithiasis c ould correctly be predicted in 11/15 cases (73%), cholecystolithiasis in 71/120 cases (59%). Conclusion: ''Single-shot'' MR-cholangiopancrea ticography is a fast and non-invasive modality which can replace i.v. cholangiography and restrict the indication for ERCP to therapeutic in dications and problem cases.
