摘　　要：目的探讨多层CT血管造影对胰腺癌胰周血管侵犯的判断及其临床意义。方法使用TOSHIBA Aquilion16层螺旋CT对胰腺癌患者进行增强扫描,动脉期和门脉期胰周主要血管CTA三维成像。分别利用三维图像和单纯轴位图像,对胰周血管是否受累进行判别及评价,并与手术对照。结果手术病人42例,CTA三维图像显示血管受侵28例,CT单纯轴位图像显示血管受侵25例,术中所见血管受侵29例。CTA三维图像判断血管受侵敏感性为93.10%,特异性为92.31%,CT单纯轴位图像判断血管受侵敏感性82.76%,特异性为92.31%。结论相对于CT单纯轴位图像,术前多层CT血管造影判断胰腺癌的胰周血管是否受侵,对手术更具有前瞻性指导意义。Objective To evaluate the state of the peripancreatic vessel encroached by pancreatic carcinoma using multi-slice CT angiography （CTA） on epigastrium, and discuss the significance of CTA. Methods Patients with pancreatic carcinoma were scanned by Toshiba Aquilion 16-detector row computed tomo- graphy （CT）. CT angiography in arterial phase and portal phase of the major peripancreatic vessel were mapped. The state of the peripancreatic vessel encroached by pancreatic carcinoma were distinguish and e- valuate both in three-dimension and purely axis images, and were compared with the state seen in operation. Results Forty-two patients underwent operation. Twenty-eight cases with major peripancreatic vessel invaded were affirmed with CTA. In them, twenty-five cases were affirmed with purely axis images. Twenty-nine cases with major peripancreatic vessel invaded were affirmed in the operation. For display of peripancreatic vessel invaded with CTA, the sensitivity was 96. 43 %, and the specificity was 92. 31%. For display of peripancreatic vessel invaded with purely axis images, the sensitivity was 82. 76% ,and the spe- cificity was 92. 31%. Conclusion Compared with axis CT images,the prediction of peripancreatic vessel invaded with CTA was significant in prospective guide for surgery.
