复合延时螺旋CT血管造影判断肺癌与大血管的关系

Judgement on Relationship between Lung Cancer and Large Blood Vessels with Compound Postpone Scan of Spiral CT Angiography

目的:对比螺旋CT血管造影(SCTA)与复合延时SCTA判断肺癌与大血管的关系,评价复合延时SC-TA的临床应用价值。方法:对9例肺癌患者进行SCTA和复合延时SCTA检查,共涉及30支血管,比较两种方法对肿瘤侵犯大血管的评价,并与手术结果比较。结果:复合延时SCTA与SCTA在判断血管明显受侵结果基本一致,且与手术结果吻合。而判断未明显侵犯血管时,复合延时SCTA有92.9％(13/14)血管与手术结果相符,SCTA只有50％(7/14)血管与手术结果相符。结论:复合延时SCTA能较确切的提示肺癌与大血管的关系。

Objective: To judge the relationship between lung cancer and large blood vessels with compound postpone scan of spiral CT angiography(SCTA) . Methods: Nine patients with lung cancer were examined with compound postpone scan of SCTA or SCTA. The judgement on central vascular involvement and surgical findings with the two methods were compared.Results: When obviously vascular involvement was found, there was not difference between the compound postpone scan of SCTA and the SCTA. When obviously vascular involvement was not found, the compound postpone scan of SCTA was exacter than the SCTA.Conclusion: The compound postpone scan of SCTA can exactly show the relationship between lung cancer and large blood vessels.
