Abstract:
Objective To investigate the diagnostic value of MR cholangiopancreatography(MRCP) and volume imaging body exam(VIBE) in the obstructive jaundice.Methods 119 patients with obstructive jaundice underwent MRI examination of upper abdomen using the special sequences of MRCP and VIBE.The qualitative diagnosis of obstructive jaundice was evaluated with MRCP and VIBE in comparison with that of percutaneous transhepatic cholangiography(PTC),endoscopic retrograde cholangiopancreatography(ERCP) and operation.Results The corresponding diagnostic rate was 94.1% for obstructive jaundice with MRCP and VIBE,of that the corresponding rate in calculus obstruction,malignant obstruction,and the benign obstruction except calculus obstruction was 100%,94.3% and 83.9% respectively.There was significant difference between malignant obstruction and benign obstructive(P
