Diagnostic accuracy of magnetic resonance cholangiopancreatography in diagnosis of obstructive jaundice

ABSTRACT

To compare the diagnostic accuracy of MRCP in diagnosing obstructive jaundice taking endoscopic retrograde cholangiopancreatography [ERCP] as gold standard. Cross sectional survey. This study was conducted Radiology and Gastroenterology Departments, Sheikh Zayed Post graduate medical Institute, Lahore for a period of Six months from August 2012 to January 2013. A total of 90 patients having history and clinical suspicion of obstructive jaundice were enrolled in this study. MRCP was obtained in all cases followed by ERCP was performed. All this information was recorded on proforma and results were evaluated. A total of 90 patients were included in the study. 40 [44.4%] were male and 50 [55.6%] were female. The age ranged from 15-80 years. Mean age of patients was 46.66 +/- 16.33 years. In our study the sensitivity of MRCP in diagnosing obstructive jaundice was found to be 86.0%, specificity 70%, positive predictive value 96.0% and negative predictive value was found to be 39.0% and diagnostic accuracy was 84.0%. The outcome of this study was that MRCP is reasonably good in diagnosing obstructive jaundice but is relatively less accurate as compared to ERCP
