Abstract:
Objective To investigate the qualitative diagnostic value of MRCP in patients with benign obstructive jaundice.Methods MRCP and conventional MR images were performed in 128 patients with benign obstructive jaundice on a superconductive MR scanner (Plilips medical systems Inc. Eclipse. 1.5T) . Final diagnosis was confirmed by surgical and histopathological findings in 123 patients and other 5 patients by follow-up.Results The accuracy of location diagnosis of MRCP was 100%; the qualitative diagnosis was 95.3%. The specificity, accuracy, sensitivity of the deadwood-sign for diagnosis of benign obstructive jaundice were 100%, 95.3%, 85.7% respectively. Conclusion The deadwood-sign was a specific indicator in MRCP of benign obstructive jaundice.
