多层螺旋CT血管成像在支气管动脉灌注化疗前的定位价值

目的探讨多层螺旋CT血管成像(MSCTA)在支气管动脉(BA)灌注化疗前的定位价值。方法分析15例经支气管动脉介入治疗前的的肺癌病例,中央型13例,周围型2例。15例均行螺旋CT增强扫描,后传至工作站利用多平面重组(MPR)、最大密度投影(MIP)和容积再现(VR)等后处理技术观察支气管动脉。结果13例中央型肺癌均由肿瘤性支气管动脉供血,重建图像清晰显示肿瘤性支气管动脉的起点、分支情况及走行特点;其中2例右侧肿瘤性支气管动脉与肋间动脉共干。2例周围型肺癌中有1例由肿瘤性支气管动脉供血,1例找不到明确发自支气管动脉的供血血管。结论多层螺旋CT血管成像能够显示肺癌特别是中央型肺癌的肿瘤性支气管动脉并能为经支气管动脉灌注化疗提供准确定位。

Multislice CT angiography in the dipiction of arterial anatomy before bronchial artery infusion in lung cancer

Objective To explore the value of CT angiography in the location of bronchial artery before bronchial artery infusion(BAI) in lung cancer.Methods Fifteen patients with lung cancers including central type(13 cases) and peripheral type(2 cases) proved by pathology were analyzed prospectively.They were all examined with contrasted MSCT and the data was send to the workstation and reconstructed with multi-planar reformation(MPR), maximum intensity projection(MIP) and volume rendering(VR).Results All cases of central type were supplied by the bronchial artery and two were by the bronchial artery and intercostals artery.One case of peripheral lung cancer was supplied by the bronchial artery and the other could not find the determined supplying artery.Conclusion MSCT angiography showed great value in the locating of BA before the BAI in lung cancer.
