胰腺恶性肿瘤的切除率不高，传统上需经剖腹才能确定，现CT扫描已成为术前分期的重要方法。作者自1989～1994年应用CT扫描评估胰腺癌切除率的准确性以及对生存期的影响。CT扫描图象的分析内容有：（1）肿瘤局部扩展范围；（2）胰腺周围主要动静脉被完全或部分包裹程度；（3）有 The resection rate of pancreatic malignancy is not high, and it is traditionally determined by caesarean section. CT scan has become an important method for preoperative staging. The authors used CT scans from 1989 to 1994 to assess the accuracy of pancreatic cancer resection rates and their impact on survival. The CT scan image analysis includes: (1) the extent of tumor local expansion; (2) the degree of complete or partial envelopment of major arteriovenous lines around the pancreas; (3)
