Abstract

To compare the diagnostic accuracy of computed tomography (CT) and magnetic resonance imaging-magnetic resonance cholangiopancreatography (MRI-MRCP) in assessing the level and cause of obstruction in patients with obstructive jaundice, and to corroborate the preoperative diagnostic accuracy of MRI-MRCP and CT with operative findings.This prospective study included 40 patients with operable obstructive jaundice, whose ages ranged between 20 and 70 years. Diagnosis was based on clinical history, physical examination, biochemical examination, and ultrasonography, followed by CT and MRI-MRCP. The findings of these imaging modalities were compared with intraoperative findings. A statistical analysis was performed to determine the efficacy of CT scanning and MRI-MRCP.CT is a better modality for diagnosing malignant causes of obstructive jaundice while MRI-MRCP shows excellent results in detecting benign causes.MRI-MRCP is an excellent modality for the detection of common bile duct stones, but it has its limitations regarding visualization of the periampullary region, whereas CT scanning proved to be useful in delineating the malignant causes of obstruction.
