摘　　要：目的探讨多层螺旋CT(MSCT)重建技术在胰腺癌诊断及手术可切除性评估中的应用价值。方法回顾性对35例经手术证实的胰腺癌患者的多期增强CT图像进行后处理,包括容积重建(VR)、多平面重建(MPR)和曲面重建(CPR),重点观察胰腺肿瘤与周围结构及邻近血管、胆管的关系,并与手术结果对照。结果 35例患者多期增强CT扫描可清晰显示肿瘤的部位、大小,重建图像可更直观显示动静脉、胆管受侵后的改变及淋巴结的情况。35例患者中CT评估手术可切除21例(行胰腺癌根治术19例,姑息术2例),不可切除14例(行姑息术14例)。根治术、姑息术术前评估与术后符合率分别是90%和88%。结论 MSCT后处理技术对胰腺癌的诊断有重要价值,有助于术前治疗方案的选择和可切除性的评估。[Objective]To explore the value of MSCT reconstruction technique for diagnosis and preoperative evaluation of pancreatic carcinoma.[Methods]Thirty-five cases of pancreatic carcinoma proved histologically were analyzed retrospectively. The techniques of volume rendering （VR）, multi-planar reconstruction （MPR） and curved planar reformation （CPR） were used to deal with the obtained images, the relation between the pancreatic tumor and its surrounding structures were observed, and then were compared with operative results.[Results]Thirty-five cases images obtained by multi-phases enhanced CT showed the location and size of tumors clearly, furthermore, the changes of blood vessel, lymph node and biliary ducts were illustrated by reconstructive images more directly. 21 cases （19 total resection and 2 partial resection） could be operated and 14 cases （14 total resection） could not accord preoperative MSCT assessment, and the coincidence percentage of total resection and partial resection were 90% and 88% , respectively, compared with operative results. [Conclusion]MSCT reconstruction technique is useful for diagnosis and preoperative evaluation of pancreatic carcinoma.
