... ERCP, which should be used only in cases where intervention is being contemplated. Method: In this present study we have prospectively examined 38 patients with obstructive jaundice using Ultrasound and MRCP. Results: Of the thirty eight patients, one hundred and one patients had benign causes of obstructive jaundice while fifty two patients had malignant causes of obstructive jaundice. MRCP had an accuracy of 95.45% in detecting the cause of obstructive jaundice while USG had a accuracy of 81.63%. The performance of MRCP when compared to USG was statistically more significant (p<0.05). Conclusion: Assessment of obstructive jaundice and its cause, site and area of involvement of the lesion, MRCP proves to be better imaging modality over other modalities like ultrasound. It also has added advantage of being non invasive procedure with no ionization radiation.
