目的利用计算机断层扫描血管造影(computed tomography angiography,CTA),回顾性分析肺癌与炎症两种不同病变的病人支气管动脉(bronchial artery,BA)特征。方法收集116例患者胸部CT增强原始图像,结合横轴位图、最大密度投影(maxium intensity projection,MIP)、多平面重建(multiple planar reconstruction,MPR)、三维(three dimensional,3D)图像,进行BA重建,并测量相关数据。结果共显示BA236支。肺癌组74例,69例BA显示,共计BA170支,平均2.46支,病灶同侧显示131支;炎症对照组42例,36例见BA显示,显示BA66支,平均1.83支,其中病灶同侧显示49支;经统计学分析,肺癌组同侧与炎症组同侧BA内径无明显差异(P>0.05);肺癌组同侧总横截面较炎症组同侧BA增大(P=0.000<0.05)。结论 CTA能清楚的显示BA的形态、走行及分布,通过测量BA的内径可以为研究肺癌与炎症两种不同性质的肺部疾病中BA血流量的改变提供参考。
Objective To analyze the features of bronchial artery (BA) in patients with two different pathological types of lung cancer and inflammation using computed tomography angiography (CTA). Methods One hundred and sixty-six patients with primary thoracic CT enhancement were enrolled in this study. A total of 116 cases of primary thoracic CT enhancement images were collected and compared with horizontal axis, maxium intensity projection (MIP), multiple planar reconstruction (MPR) and three dimensional (3D) Reconstruction, and measurement of relevant data. The results showed a total of BA236 branch. 74 cases of lung cancer, 69 cases of BA showed a total of BA170, an average of 2.46, the lesion ipsilateral 131; inflammatory control group of 42 cases, 36 cases of BA showed BA66 branch, an average of 1.83, of which the lesion ipsilateral display There was no significant difference in ipsilateral BA diameter between ipsilateral group and inflammatory group in lung cancer group (P> 0.05). The ipsilateral BA cross-section in lung cancer group was higher than that in inflammation group (P = 0.000 <0.05) . Conclusion CTA can clearly show the morphology, migration and distribution of BA. It can provide a reference for the study of the changes of BA blood flow in lung diseases with different lung diseases and inflammatory diseases by measuring the internal diameter of BA.
