Accuracy Of MDCT Cholangiography Using Image Reformation In Cases Of Biliary Tract Obstruction Comparing With ERCP.
Isra Med J Jan ;8(4):220-3.

OBJECTIVE: To determine the diagnostic accuracy of multidetector computed tomography cholangiography in diagnosis of biliary tract obstruction keeping Endoscopic Retrograde Cholangiopancreatogram (ERCP) as gold standard. STUDY DESIGN: A Cross Sectional Validation Study PLACE AND DURATION: The study was done in the Department of Radiology, KRL Hospital Islamabad, from 1st may 2013 to 31st October 2013. METHODOLOGY: All patients included in the study underwent contrast enhanced CT scan using Toshiba Aquilion 64 slice CT scanner. Reformated cholangiographic images were produced using a workstation (Vitrea, version 3.9)Final multidetector computed tomography diagnosis was later on compared with ERCP done and reported by an endoscopy specialist. Both qualitative and quantitative variables were calculated. RESULTS: In our study two age groups i.e 20-40years and 41-60years were included, mean age was calculated as 36.81+/- 9.72 years, with 57.27% were male and 42.73% were females. The frequency of biliary tract obstruction diagnosed on Endoscopic Retrograde Cholangio-Pancreatography (ERCP) was recorded in 60.91%. Diagnostic accuracy of MDCT cholangiography in diagnosis of biliary tract obstruction shows 55.45% true positive,2.73% false positive, 37.27% true negative and 5.45% false negative values. CONCLUSION: From study it can be concluded that MDCT cholangiography can be reliably used as tool in diagnosis of biliary tract obstruction in comparison with ERCP.
