摘　　要：目的:探讨多层螺旋CT(MSCT)三维后处理动静脉分离技术在周围型肺癌中的应用价值。方法:分析周围型肺癌97例和炎性结节35例,利用三维后处理技术分离出肺静脉,并与病理对照,分别观察周围型肺癌对肺动脉、静脉的侵犯情况。结果:97例周围型肺癌共侵犯肺血管351支,侵犯肺静脉244支,占69.5%;35例。对照组中,炎性结节侵犯肺血管120支,侵犯肺静脉56支,占46.7%,两者差别有统计学意义(P<0.001)。以UICC肺癌分期标准,将患者分为Ⅰ期、Ⅱ期、Ⅲ期,分别计算其静脉侵犯率为51.2%、71.0%及88.0%,差异具有统计学意义(P<0.001)。结论:多层螺旋CT增强扫描及三维后处理技术能够清晰显示肺癌侵犯肺动脉、肺静脉情况,周围型肺癌侵犯肺静脉数量明显多于肺动脉,在肺癌的诊断及判断病期中具有重要的应用价值。Objective：To investigate the application value of the technique of multi-slice spiral CT（MSCT）3D arterio-venous separation in the peripheral pulmonary cancer.Methods：Analyzed the invasion of 97 patients who had peripheral pulmonary cancer by the means of MSCT 3D arterio-venous separation and pathology respectively.Set 35 inflammatory nodules for the matched control.Results：The 97 peripheral pulmonary cancer totally infringes upon afferent 351 vessels and 244 lung veins（69.5%）.In 35 matched controls,nodules infringe upon 120 vessels and 56 veins（46.7%）.The difference is significant（P0.001）.The patients are divided intoⅠ,Ⅱ,Ⅲ stage by UICC lung cancer staging system,and the ratio of the vein invasion is 51.2%,71.0% and 88.0% respectively.The difference is significant（P0.001）.Conclusion：MSCT 3D arterio-venous separation by post-processing techniques can show the infringe upon lung artery and vein in the peripheral pulmonary cancers.It can be applied in the diagnosis and judgment disease of the peripheral pulmonary cancers.
