ROLE OF MAGNETIC RESONANCE IMAGING IN PREDICTING INFECTION IN PANCREATICO–BILIARY DISEASES

Dr. Abhishek Chauhan, Dr. Gaurav Raj, Dr. Ragini Singh

Abstract :

Background: Acute Pancreatitis has been defined as an acute, mainly diffuse, inflammatory process of the pancreas with associated intermediate (2–5 weeks) complications like infected necrosis, pancreatic abscesses, etc. Biliary infections or ascending cholangitis is a clinically defined syndrome caused by complete / or partial biliary obstruction with associated ascending infection from the intestine. Materials and Methods: Study comprised of 31 patients [22 with biliary system collections and 9 with pancreatic collections were prospectively scanned using an integrated MR examination that included T1 weighted, T2 weighted, and Diffusion weighted echo planer imaging (DW–EPI) sequences. All the patients were subjected to radiological intervention drainage/aspiration procedure within 48–72 hrs of the imaging study for their management. Results: DW–EPI data of 31 patients with pancreatico–biliary collections 12 were microbiologically proven infected and 19 were sterile. 8 among the 12 showed diffusion restriction on ADC while 4 showed T2–shine through effect. Remainder of 19 patients with microbiologically proven sterile collections reveals absence of any restriction. Conclusions: Based on Receiver operator curve (ROC) analysis, at ADC levels <3, the sensitivity of the test was 75% while specificity was 63.16%. The negative predictive value was reasonably high (80%). Thus the test could be used efficiently as a screening tool.
