Background & Objective: The main objective of the study is to determine the accuracy of MRCP over CT in the evaluation of patients with obstructive jaundice. Material & Methods: The study was conducted in the department of Radio Diagnosis, for a period of 1 and a half year from July 2015-December 2016. Thirty six patients were included in the study. All the patients were referred to the department of radio diagnosis with the clinical suspicion of obstructive jaundice and elevated serum bilirubin levels. CT and then MRCP were done in all the patients. The accuracy of each modality was analysed statistically and correlation was made with the surgical findings or histopathological reports. Results: Of the thirty six patients, sixteen patients had benign causes of obstructive jaundice while twenty patients had malignant causes of obstructive jaundice. For diagnosing the cause of obstructive jaundice MRI with MRCP has a greater diagnostic accurancy of 94.4% than helical CT with accuracy of 91.6%.The sensitivity of MRI with MRCP is greater than that of helical CT in diagnosing the cause of obstructive jaundice. In diagnosing the site of obstruction. MRCP had a accuracy of 100% while CT had 88% .The performance of MRCP when compared to CT was statistically more significant (p<0.05). Conclusion: In the diagnosis of obstructive jaundice and to know the cause, site and extent of the lesion MRCP being a non invasive, non ionizing procedure seems to be a better choice over CT. The only drawback of MRCP is the cost involved and the availability.
