CT对急性胰腺炎的诊断价值

CT diagnosis of acute pancreatitis

目的评价CT在急性胰腺炎诊断和分型中的作用。方法95例经临床与手术证实的急性胰腺炎患者均进行屏气CT扫描,其中,14例进行增强扫描,30例患者进行多次扫描。结果本组95例中,80例诊断为急性水肿型胰腺炎,表现为胰腺肿大水肿,胰周间隙和肾旁前间隙蜂窝织炎,实质密度不均匀,另15例诊断为出血坏死型胰腺炎,除有上述表现外,还可见出血坏死区域。结论CT对急性胰腺炎的诊断和分型具有重要作用。

Objective To assess the utility of computed tomography（CT） in the diagnosis and the typing of acute pancreatitis. Methods Ninety - five patients with clinically and surgically proved acute pancreatitis underwent routine CT seans of the abdomen under hold breath. 14 patients underwent additional contrast - enhanced scans. 30 patients underwent several times of scans. Results Among 95 cases, 80 cases were diagnosed as acute edematous - type of pancreatitis because they presented pancreatic edema and enlargement, cellulitis of peripancreeatic and pararenal anterior spaces, and heterogeneous density of pancreatic parenchyma on CT images. Other 15 cases in the group presented necrotic - hemorrhagic areas besides above CT findings and therefore they were diagnosed as hemorrhagic, necrotic - type of pancreatitis. Conclusion CT plays a major role in the diagnosis and typing of acute pancreatitis.
