BACKGROUND AND OBJECTIVES : Objective of our study was to diagnose pancreatitis by ultrasound and computed tomography and to define limitations and advantages of one modality over other. MATERIALS AND METHODS : We studied findings of acute and chronic pancreatitis on two modalities i.e. ultrasound and C.T between 16–62 years of age from March 2019 to February 2020. Patients were confirmed to have pancreatitis based on imaging findings on eithermodality and a combination of clinical features suggestive of pancreatitis and biochemical values to support a diagnosis of the same. In acute pancreatitis, CT severity index also taken into consideration. The index focuses on the presence and degree of pancreatic inflammation and necrosis on a 10 point severity scale, points are awarded for the presence or absence of fluid collections. Patients in whom the diagnosis of pancreatitis was made purely on clinical grounds without any imaging (ultrasound or CT) and patients in whom no imaging was done prior to surgery where a diagnosis of pancreatitis was made was excluded from the study. RESULTS : Epigastric pain is the most common symptom in acute pancreatitis. Mostly the patients are alcoholic. It affects males more than females. In our study 81% of patients are males. CONCLUSION: Ultrasound is the initial investigation for pancreatitis but CT is investigation of choice. Ultrasound sometimes is not accurate because of bowel gas and other techniqual problems. Alteration in the size and echogenicity were the most common ultrasonography findings. Bulky hypoechoic pancreas was considered diagnostic of acute pancreatitis on ultrasonography. Duct dilatation and calcification were seen in chronic pancreatitis on ultrasonography
