Introduction: Pancreatitis is one of most complex and clinically challenging of all abdominal disorders. USG and abdominal CT are the most commonly used diagnostic imaging modalities for the evaluation of pancreas. Computed Tomography (CT) is highly accurate and sensitive than USG in both diagnosing as well as demonstrating the extent. Early assessment of the cause and severity of acute pancreatitis is of utmost importance for prompt treatment and close monitoring of patient with severe disease. CT is the imaging method of choice for assessing the extent of acute pancreatitis and for evaluating complications. Materials and methods: This is a prospective study was conducted in the Department of Radiology at Dr. VRK Women's Medical College, Teaching Hospital and Research Centre Hyderabad, among 70 cases of acute pancreatitis. All the cases of acute pancreatitis referred under department of radiology in a tertiary healthcare institute, and fulfil the set inclusion criteria, who consented to participate in the study were included in the present study. It was carried out among 46 indoor cases of acute pancreatitis referred under department of radiology for further diagnostic evaluation, in a tertiary healthcare teaching institute in Maharashtra during study period. Ethical Approval was taken from the college ethics committee. Result: In our study, a total 70 patients were studied using CT scan, who was suspected to have acute pancreatitis. Among them, 50 (71.5%) were males and 20 (28.5) were females. Necrosis of the pancreatic gland parenchyma was seen in 17 (24.3%) patients. 12 patients (17.1%) showed <30% necrosis. 8 patients (11.4%) showed 30-50% necrosis, and 10 patients (14.3%) showed more than 50% necrosis. Conclusion: In conclusion CECT was found to be an excellent imaging modality for diagnosis, establishing the extent of disease process and in grading its severity. The Modified CT Severity Index is a simpler scoring tool and more accurate than the Balthazar CT Severity Index. In this study, it had a stronger statistical correlation with the clinical outcome, be it the length of hospital stay, development of infection, occurrence of organ failure and overall mortality. It could also predict the need for interventional procedures
