Background: Obstructive jaundice is a common pathological problem that occurs when there is an obstruction to the passage of conjugated bilirubin from liver cells to intestine. Bile, a digestive fluid secreted and produce by the liver. Most common cause of obstructive jaundice is due to gallstones. Objective: The aim of our study was to evaluate the diagnostic Efficacy of MRCP and Ultrasound on obstructive jaundice. Study design: A cross-sectional prospective study was performed. Material & Method: A cross-sectional prospective study was performed in 50 patients who came with the provisional diagnosis of obstructive jaundice were referred to ultrasound for primitive diagnosis and were then shifted to MRCP for a detailed diagnosis. The data was collected from the outpatient department facility of Pakistan Kidney and Liver Institute Hospital, Lahore. After informed consent, data was collected from MRI GE 1.5 Tesla, Ultrasound Canon Xanio. Results: The results revealed that there are 50 patients of obstructive jaundice. 20 were females’ patients and 30 were males’ patients, with age raging from 20-40 years. There were 17 patients out of 50 in our study which ultrasound showed negative results that were positive on MRCP there were 28 patients that were positive on both ultrasound and MRCP. There were 3 patients that were positive on ultrasound but negative on MRCP and 2 patients that were negative on both modalities Conclusion: Our study concluded that higher ratio of males then females in our sample size, RHC was positive in all the patients with dominant cause of jaundice was stone with in biliary channel. We found that MRCP has better efficiency comparative to ultrasound to detect jaundice and its etiology i.e., 90% true positive.
