Diseases of the biliary tree and the pancreas are common in India and worldwide. Causes of bile duct obstruction may be benign or malignant. Benign causes may be due to intraluminal causes e.g. Choledocholithiasis, Haemobilia or parasites. Non- invasive imaging modalities of biliary system include USG, CT. Invasive methods include direct cholangiographic methods like ERCP, Percutaneous Transhepatic Cholangiography (PTC) and Intraoperative Cholangiography. USG is the primary screening modality. This prospective study was done to evaluate the role of MRCP as a non-invasive diagnostic tool in patients with suspected obstructive biliopathies and to compare and correlate the MRCP findings with those of other modalities. MRCP was comparable with Direct Cholangiography in identifying the level of block in 57 of 60 cases (95%) MRCP showed high sensitivity (100%) and diagnostic accuracy (96.29%) in identifying the level of block. MRCP is not only comparable with direct cholangiography in its diagnostic ability, but it has the tremendous advantage of being noninvasive. MRCP is still an evolving technique, it has established itself as clinically useful noninvasive investigation and comparable with direct cholangiography for the evaluation of various pancreatic or biliary ductal diseases.
