Aims and Objectives:1.To identify the CT features of clinically suspected acute pancreatitis and grade the features according to modified CT severity index.2.to correlate the modified CT severity index with clinical outcome of patients.

Materials and Methods: Contrst enhanced CT scan was done in 50 patients referred from various clinical departments to the department of radio diagnosis, V S S Institute of Medical Science and Research, Burla. Study period was sept 2014 to sept 2016. CT features were scored according to modified CT severity index. Patients complications which were taken into consideration non the basis of duration of hospital stay, organ failure, surgical intervention, systemic infection and mortality.

Results and Conclusion: modified CT severity score was found to be significantly correlated with organ failure (p<0.002), systemic infection (p=0.001) and duration of hospital stay(p<0.01). The inclusion of extra pancreatic parenchymal complication in the modified CT severity scoring makes it a better prognostic indicator than CT severity scoring, used earlier ,for assessing adverse clinical outcomes in patients with acute pancreatitis.
