胰腺癌临床表现隐慝 ,临床诊断困难。随着CT技术的发展 ,螺旋CT、多层螺旋CT的运用 ,多期扫描、血管重建等功能的实现 ,使CT成为胰腺癌诊断及评价的重要手段之一。本文着重介绍螺旋CT在胰腺癌的诊断及鉴别诊断、术前分期及其手术切除的可能性评价的重要作用 ,对胰腺癌的发病机制、临床特征和病理及CT扫描技术等方面也作了简介 Clinical manifestations of pancreatic cancer hidden, difficult clinical diagnosis. With the development of CT technology, the application of spiral CT, multi-slice spiral CT, multislice scanning and revascularization make CT become one of the important methods for the diagnosis and evaluation of pancreatic cancer. This article focuses on the important role of spiral CT in the diagnosis and differential diagnosis of pancreatic cancer, preoperative staging and the possibility of surgical resection, and also introduces the pathogenesis, clinical features and pathology and CT scanning techniques of pancreatic cancer
