Abstract
Background: Evaluation of jaundice patients should include proper history and examination,
laboratory investigation and imaging investigations (non invasive like Ultrasound (U\S), CT and
MRI or invasive like ERCP and PTC).
Aim of Study: The aim of this prospective study is to evaluate the diagnostic reliability of U\S and
MRI-MRCP in patients of obstructive jaundice in clinical practice. Materials and Methods: This is a prospective study performed on 60 patients (31 male and 29
female) with an average age of 55.53 +/- 17.57 years presented with obstructive jaundice for whom
abdominal ultrasound (U\S) and magnetic resonance imaging (MRI) and magnetic resonance
cholangiopancreatography (MRCP) on 3 Tesla was performed in the departments of radiology in
Max super speciality teaching hospital, saket, Delhi, India from May 2012 to May 2013. The final
diagnosis was achieved by endoscopic retrograde cholangiopancreatography (ERCP) and \or
surgery and confirmed by histopathology.
Results: The most common cause of obstructive jaundice in our study was common bile duct
stones (51.65%) followed by tumors (33.3%) then benign strictures (10.0%), choledochal cyst
(3.33%). In this study, MRI-MRCP could differentiate surgical from medical jaundice in all cases,
while U\S could differentiate surgical from medical jaundice in 91.25% of cases. MRI-MRCP
correctly defines the level of obstruction in all cases (100%). While U\S correctly define the level of
obstruction in only 78% of the total cases. MRI-MRCP correctly suggests the most possible cause
of obstruction in 96.25% of cases. While USG is correctly suggests the most possible cause in only
76.3%.
Conclusion: So that USG as a screening modality is useful to confirm or exclude biliary dilatation
& to choose patients for MRCP examination. MRI-MRCP is a useful non-invasive and essential
method in the preoperative evaluation of patients with obstructive jaundice. In addition MRI-MRCP
was superior to U\S or ERCP in studying the extent & staging of malignant lesions.
