Aim: The goal of the radiological study is to determine the accuracy of MRCP over USG and CT in diagnosing cases with obstructive jaundice. Methods: The Department of Radiology performed a cross-sectional prospective research. This research comprised 50 individuals with clinically confirmed obstructive jaundice and total bilirubin levels more than 5mg/dl. All patients in the research had a USG examination first, then an MRCP, and lastly a CT scan. Results: Twenty of the 50 individuals had benign lesions, whereas 30 had malignant lesions. MRCP detects the location of blockage with 96% accuracy, followed by CT and USG. The sensitivity of MRCP and CT is the same, but USG has a sensitivity of 96%. Despite the high sensitivity of USG, the specificity is quite poor at 62% when compared to CT's 62% and MRCP's 96%. Thus, USG is an excellent screening technique for benign obstructive jaundice lesions, but CT and MRCP are the specific investigations. With an accuracy of up to 96%, the MRCP is once again the most accurate examination. MRCP has a high sensitivity and specificity, making it more accurate. While USG and CT have great sensitivity, their specificities are poor. The MRCP has the biggest area of the three studies, demonstrating that it is the most effective in detecting malignant lesions. Again, the p value is more than 0.05, indicating that it is significant. Thus, in the diagnosis of obstructive jaundice, MRCP is statistically more significant than CT and USG. Conclusion: In the diagnosis of obstructive jaundice and to determine the aetiology, location, and size of the lesion, MRCP seems to be a better option than other radiological techniques such as USG, CT, or ERCP.
