胰腺肿瘤术前准确的可切除性评估可避免不必要的手术创伤及合理利用有限的医疗资源。目前的评估方法主要依靠CTA。但是，由于CTA影像学评估存在一些缺陷，常常导致错误地判断。采用腹部医学图像三维可视化系统对腹腔血管及胰腺肿瘤进行三维重建，3D模型可清晰的显示肿瘤和周围血管的空间立体关系，并在此基础上提出可切除性评估的标准。数字医学技术的应用，对提高胰腺肿瘤诊断的正确性和手术切除的成功率，具有重要的临床应用价值。

Abstract    Accurate assessment can eliminate unnecessary surgical trauma, fully utilize limited medical resources, and provide patients with the most appropriate treatments. Currently, CT angiography (CTA) is a common imaging technique used to assess tumor resectability; however, this method has some imaging techniques defects. Abdominal vascular and pancreatic neoplasm, reconstructed by the Medical Image Three-dimensional Visualization System of Abdomen can clearly show the spatial relationship between tumor and its peripheral vascular, which allowed us to establish a set of novel criteria for resectability assessment to conduct preoperative auxiliary diagnosis and resectability assessments. Digital medical technology could perform a high value of clinical practice by improving the accuracy of the diagnosis and the success rate of the resection of pancreatic cancer.
