Background: To assess the severity of acute pancreatitis (AP) using computed tomography (CT) severity index (CTSI) and modified CT severity index (MCTSI), to correlate with clinical outcome measures, and to assess concordance with severity grading, as per the revised Atlanta classification (RAC).

Material and Methods: This is a prospective study, conducted from August 2019 to July 2020, in the Department of Radiology, Al Ameen Medical College. A total of 70 patients referred from the Department of Medicine and Department of Surgery, presented with the chief complaint of epigastric pain, nausea and vomiting and CECT abdomen were suggestive of acute pancreatitis were included in this study. Assessment of severity of acute pancreatitis was done in all cases by Balthazar CTSI scoring and Mortele Modified CTSI scoring.

Results: In the present study total 70 cases of acute pancreatitis cases were included in the study. These patients underwent CT abdomen and pelvis, later images were reviewed by the radiologist. The maximum patients were in the age group of 21 to 40 years [n=33 (47.1%)]. Majority of the cases were categorized as mild pancreatitis according to Balthazar CTSI score. Majority of the cases were categorized as severe pancreatitis using the Modified Mortele CTS score. Whereas, organ failure, moderate and severe category in modified Mortele CTSI, mild, moderate, severe category in Balthazar CTSI.

Conclusion: In conclusion CECT was found to be an excellent imaging modality for diagnosis, establishing the extent of the disease process and in grading its severity.
