16层螺旋CT三维重建技术在结直肠癌外科治疗中的应用

目的探讨16层螺旋CT三维重建在中晚期结肠癌外科治疗中的应用价值。方法回顾分析43例经过手术证实的结肠癌病例,术前均进行平扫和三期扫描,所有病例均进行三维重建。结果浆膜层浸润准确率95%（35/37）,淋巴结转移准确率77%（10/13）,远处脏器转移准确率62%（8/13）,显示肿块准确率100%（43/43）,显示供血血管准确率100%（24/24）。结论16层螺旋CT三维重建可以更好的显示病灶及病灶与周围脏器的关系,为外科手术治疗提供独特的信息。

Application of three- dimensional (3D) reconstruction with 16- slices spiral CT in oncological surgery of rectum and colon cancer

Objective To investigate the application of three - dimensional （3D）resconstruction with 16 - slices spiral CT in oncological surgery of rectum and colon cancer. Methods Both plain and three - phase contrast enhanced and 3D CT in 43 cases with pathologically proved colon cancer were analyzed retrospectively. Results CT images showed diagnostic accuracy of invasion to serous membrane was 95 % （35/37）, lymphadenopathy was 77 % （10/13）, metastasis was 62% （8/13）, mass for 100% （43/43）, the blood - supply vessels for the tumors was 100% （24/24）. Conclusion The leision＇ s location and its relationship with its surroundings can be shown more clear by three- dimensional （3D） reseonstruction with 16 - slices spiral CT ,which will particularly provide valuable information for surgical therapy .
