ABSTRACT
Objective To evaluate the diagnostic value of the low field MRCP in obstructive jaundice by comparing its result with that of US and CT. Methods 55 cases of obstruction jaundice patients proved by clinical diagnosis were studied and compared the collected original diagnosis results by low filde MRCP with US and CT.Results Of 55 cases of obstructive jaundice, 30 were cholelithiasis ,21 were tumors and 4 belonged to the other type. The accuracy of MRCP for defining the site of obstruction was 100%. The accuracy for identifying the cause of obstruction was 81.8%.Conclusion The low filde MRCP can accurately define the obstructive site in biliary obstructive disease .When used together with 2D single-shot breath-hold MRCP , T 2WI, T 1WI and 3D-FSE MRCP shows high accuracy and sensitivity in diagnosing obstructive jaundice.
