This retrospective study compared imaging results with surgery findings in 26 choledocholithiasis patients who were examined with two-dimensional fast spin-echo (2D-FSE) MR cholangiography and half-Fourier acquisition single-shot turbo spin-echo (HASTE) MR cholangiography. Patients were examined using a 1, 5 T Philips Gyroscan ACS\11 MR scanner and a 1 T Siemens Harmony MR scanner. A total of 21 of the 26 patients with diagnosed choledocholithiasis on imaging were proven to have common bile ducts stones. Two patients had another small stone which was impacted into the Vater and which was not detected with MR cholangiography. One patient with mild dilated common bile duct and pancreatic duct also had a small impacted stone which was not detected by MR cholangiography. One patient had an irregular stone in the hepatic duct, extending partially into the left hepatic duct which was misintepretated as carcinoma. The last patient had a dilated common bile duct due to a small impacted stone which was not detected and biliary sludge which was misintepretated as a stone. The overall sensitivity of MR cholangiography in the detection of common bile duct stones was 80.8%. In conclusion MR cholangiography can rapidly evaluate the common bile duct for stones. The only problem we encountered was in the evaluation of small impacted stones at the Vater. (Dig Endosc 1999; 11: 220-224)
