Abstract: This paper investigated the application of abdominal CT scan in the diagnosis and prognosis prediction of acute pancreatitis. The clinical data of 164 patients with acute pancreatitis were retrospectively analyzed. The abdominal CT imaging features of acute pancreatitis were analyzed and the complications and death were used as the prognostic criteria. Logistic regression analysis was used to identify the risk factors of complications and death in patients with acute pancreatitis. Bahhazar-CTSI scoring system was used to grade the patients' condition, and the incidence of complications and mortality of patients with different CTSI scores were compared. The relationship between severity of acute pancreatitis and complications and death were analyzed. In 164 cases of acute pancreatitis patients, the incidence rate was 51.83%, the mortality rate was 7.32%. The complications and death of patients with acute pancreatitis were related to fatty liver, invasion of bare area of stomach, invasion of adrenal gland, effusion of suprahepatic space and invasion of perirenal space (P<0.05). The severe fatty liver, gastric bare area invasion, adrenal gland invasion, suprahepatic space effusion and perirenal space invasion were risk factors for complications in patients with acute pancreatitis (P<0.05), and gastric bare area invasion, adrenal gland invasion and suprahepatic space effusion were risk factors for death in patients with acute pancreatitis (P<0.05). Bahhazar-CTSI score was positively correlated with the incidence of complications and mortality in patients with acute pancreatitis (r=0.657, 0.688, P<0.05). Abdominal CT imaging of acute pancreatitis has characteristic signs, which can clearly show the degree of pancreatic lesions and the involvement of surrounding tissues and organs, which has high predictive value for the diagnosis and prognosis of acute pancreatitis.
