目的探讨与分析CT应用于胰腺 癌与自身免疫性胰腺炎的鉴别价值。方 法 选取我院所收治的16例胰腺癌和16例 自身免疫性胰腺炎患者分别采用CT检查， 比较2者胰腺肿胀或局灶性密度减低及强 化方式、被膜样边缘、血管受侵犯、钙 化、假囊肿形成、胰管改变、肾脏受累情 况。结果 2组胰腺肿胀和局灶性密度减低 及弥漫性强化减低、被膜样边缘、血管受 侵犯、胰管截断、肾脏受累存在明显差异 性(P<0.05)。结论 临床采用CT用于诊断 胰腺癌与自身免疫性胰腺炎可提供准确信 息，进而为临床鉴别提高重要参考价值。

Objective To discuss and analyze the application value of CT in the differential diagnosis of pancreatic cancer and autoimmune pancreatitis. Methods 16 cases with pancreatic cancer and 16 cases with autoimmune pancreatitis were performed with CT in our hospital. The pancreatic edema or focal decreasing of density and enhancement pattern, the edge, vascular invasion, calcification, pseudocyst formation, pancreatic duct changes and renal involvement were compared between the two groups. Results The differences of pancreatic edema or focal decreasing of density and enhancement pattern, the edge, vascular invasion, pancreatic duct changes and renal involvement between the two groups had statistical significance (P<0.05). Conclusion The clinical use of CT for the differential diagnosis of pancreatic cancer and autoimmune pancreatitis could provide accurate information and has important value for clinics.
