BACKGROUND Obstructive jaundice due to bile duct calculus is one of the frequent clinical problems which needs proper diagnosis before initiation of treatment. USG and MRCP play a very important role to diagnose such calculus. MATERIALS AND METHODS Initial USG evaluation of patients with Obstructive Jaundice was done. Then those patients having biliary obstruction due to calculus or due to causes not detected by USG were subjected to MRCP. RESULTS Detection rate of calculus by USG In comparison to MRCP- 1) Proximal bile duct- 92.85%. 2) Distal bile duct - 77.27%. CONCLUSION USG should be done as initial examination which provides a guide to choose patients for MRCP examination in detecting bile duct calculus.
