摘　　要：目的熟悉腹部相关的解剖结构,全面认识急性胰腺炎(AP)的CT表现。方法39例经临床确诊的AP病例均行螺旋CT平扫加增强。结果2例为急性水肿性胰腺炎,表现为胰腺体积轻度增大,胰周脂肪间隙模糊;37例为急性坏死性胰腺炎,胰腺内均有低密度区,范围不等,渗出液明显,累及腹腔及腹膜后间隙,范围广泛,其中并发假囊肿者13例,脓肿1例,胰周小静脉扩张15例,伴有肠胀气者20例,胸腔积液29例。结论熟悉腹部相关结构的解剖基础有助于全面正确地认识AP的CT表现,对临床治疗有重要指导意义。Objective To understand completely the CT appearances of acute pancreatitis,and to know the concerning anatomic bases of abdomen. Methods 39 patients with acute pancreatitis confirmed by clinic underwent plain scan and enhanced scan with spiral CT. Results 2 patients were acute edematous pancreatitis,pancreates swollen slightly,peripancreatic fat became vague; 37 patients were acute necrotizing pancreatitis, there werelow-density areas in gland, accompa nied obvious exudation,inflammation involved extensively abdominal cavity and retroperitoneal spaces. Of the 37 cases,13 cases accompanied pseudocyst, 1 case with abscess, 15 case with dilated small peripanereatic veins,20 eases with dis tended intestine where there was much gas in it,29 cases with pleural effusion, Conclusion Knowing the concerning ana tomic bases of abdomen is helpful to understand completely the CT appearances of acute panereatitis.
