The Radiological Study to Establish the Accuracy of MRCP over USG & CT in Diagnosing the Case of Obstructive Jaundice

Radiological Study to Establish the Accuracy of MRCP over USG & CT

Abstract

Background: MRCP is a relatively new MR imaging technique that has revolutionized the imaging of biliary and pancreatic ducts. Methods: The study was conducted in the department of Radio Diagnosis, MGMC&RI, for a period of 2 years. Thirty three patients of obstructive jaundice were included in the study. Ultrasonography followed by MRCP and then CT were done in all the patients. Three experienced radiologists reviewed the images separately and evaluated the cause and site of obstruction in these patients. The accuracy of each modality was analyzed statistically and correlation was made with the surgical findings or histopathological reports. Results: MRCP had an accuracy of 97% in detecting the cause of obstructive jaundice while CT & USG had a accuracy of 82% & 67% respectively. In diagnosing the site of obstruction MRCP had a accuracy of 100% while CT had 88% and USG 55%. The performance of MRCP when compared to CT and USG 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 other radiological procedures like USG, CT or ERCP.
