OBJECTIVES
This study aimed to determine the diagnostic accuracy of magnetic resonance cholangiopancreatography (MRCP) in choledocholithiasis, using endoscopic retrograde cholangiopancreatography (ERCP) as the gold standard.
METHODOLOGY
This retrospective, descriptive, cross-sectional study, based on data retrieved from the hospital information management system, was performed in the Radiology Department of Northwest General Hospital and Research Centre, Peshawar. Data from October 15, 2022, to October 15, 2024, was retrieved. A total of 224 patients fulfilling the inclusion criteria were included in the sample through non-probability consecutive sampling.
RESULTS
The mean age of the sample was 46.8 ± 7.8 years. The sample consisted of 59.4% males and 40.6% females. The mean BMI of the sample was 28.4 ± 2.9kg/m². On MRCP, choledocholithiasis was recorded in 65.6% of patients, and on subsequent ERCP, it was confirmed in 58.5% of patients. The sensitivity of MRCP was found to be 90.8%, and the specificity was 69.9%. The positive predictive value of the MRCP was 81% and the negative predictive value was 84.4%. The overall accuracy was 82.1%.
CONCLUSION
MRCP is a highly sensitive and specific tool for choledocholithiasis, with the additional advantage of being non-invasive. Effect modifiers, such as diabetes and hypertension, as well as the expertise of the performing physician, should be included in further studies to determine their effect on the accuracy of MRCP.
