本文总结20例经手术和或病理证实的胰腺癌的CT表现,以探讨CT对胰腺癌诊断和治疗中的价值。方法:所有病例均在术前1～2周内作CT检查前口服1%泛影葡胺,使胃肠道充盈,以利于辨认器官间的毗邻关系。扫描方法采用层厚8mm,连续扫描,平扫及静脉注射造影剂增强扫描各一次。本组20例,其中胰头癌18例(包括2例钩突部癌),体尾部癌2例。CT诊断正确者17例,占85%;诊断未定1例,误诊为慢性胰腺炎2例。20例CT表现如下:
This article summarizes the CT findings of 20 cases of pancreatic cancer confirmed by surgery and/or pathology to investigate the value of CT in the diagnosis and treatment of pancreatic cancer. METHODS: All patients were treated with 1% diatrizoate glucosamine before 1-2 weeks before surgery to fill the gastrointestinal tract to facilitate the identification of adjacent tissues. The scanning method uses a layer thickness of 8mm, continuous scanning, plain scanning and intravenous injection of contrast agent to enhance the scanning once. This group of 20 cases, including 18 cases of pancreatic cancer (including 2 cases of uncinate process cancer), body and tail cancer in 2 cases.
