Abstract :

Introduction: Obstructive jaundice is a type of jaundice that due to blockage in the flow of bile from the liver to the duodenum caused. Obstructive jaundice in the West as there is a common disease in %15 of cases and has several causes, including hepatocellular carcinoma, carcinoma of the pancreas and biliary tract stones. Measures such as ultrasound, CT scan, ERCP, PTC and recently MRCP determine to help. Despite being the gold standard diagnostic is ERCP but not a hundred percent right. So today is trying to make more use of MRCP. Objective: The purpose of this study is to compare the results of ERCP and MRCP, both inside and outside diameter of the bile ducts of the liver, the presence or absence of defects within the duct, diameter of pancreatic duct, presence or absence of space-occupying lesions of the gallbladder. Materials and Methods: The study included 36 patients over three years for MRCP Imaging Center Corp went was. Imaging results are interpreted by a skilled radiologist and the data were recorded into the questionnaire. After definite diagnose of obstructive jaundice, the patient undergo ERCP and saved that data. The results of the two methods were compared with each other.\ esults: Among the 36 patients with obstructive jaundice within 3 years, 13 women (%36.1) and 23 men (%63.9) had a mean age of 56.8 years and men 61.5 years. The sensitivity and specificity of MRCP in the diagnosis of CBD diameter Abnormality compared to ERCP (the gold standard), respectively, %97 and %100, respectively. The sensitivity and specificity of MRCP in the diagnosis of the common hepatic duct and cystic duct diameter Abnormality compared to ERCP (the gold standard), respectively, %100 and %100, respectively. The sensitivity and specificity of MRCP in the diagnosis of hepatic duct internal diameter Abnormality compared to ERCP (the gold standard), respectively, %87 and %100, respectively. The sensitivity and specificity of MRCP in the diagnosis of biliary tract filling defect, respectively, %71 and %97, respectively. The sensitivity and specificity of MRCP in the diagnosis of space-occupying lesions were both %100 sensitivity and specificity of MRCP in the diagnosis of a filling defect in the gallbladder, respectively, %100 and %68, respectively. Conclusion: MRCP has the high sensitivity and specificity for the diagnosis of abnormalities of biliary system and reduces the need for invasive imaging techniques that have morbidity and cost a lot for patient.
