Methods: Fifty patients clinically diagnosed as suffering from obstructive jaundice and total Bilirubin greater than 5mg/dl were included in this study. All the patients in the study underwent USG examination first followed by MRCP and finally CT.

Results: The 100, 43 patients had benign lesions while 57 patients had malignant lesions. While MRCP and CT had diagnosed 95 lesions, USG could diagnose all the benign lesions. However USG had diagnosed several of the malignant lesions as benign. MRCP has 99% accuracy in detecting the site of obstruction followed by CT and USG. The sensitivity of MRCP and CT is the same for both modalities while it is 99% for USG. Inspite of the high sensitivity for USG, the specificity for the same is very low at 72% when compared to that of CT’s 72% and MRCP’s 97%. MRCP is again the most accurate investigation with an accuracy upto 99%. The sensitivity and specificity of MRCP is high making it more accurate while USG and CT have high sensitivity their specificities are low. The MRCP has the largest area among the three investigations, proving it to be the most efficient investigation in the detection of malignant lesions. The p value again is >0.05 making it significant. Thus MRCP is statistically more significant CT and USG in the diagnosis of obstructive jaundice. Conclusion: We concluded that, 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 other radiological procedures like USG, CT or ERCP.
