摘　　要：目的探讨64层CTA显示支气管动脉三维解剖结构的应用价值。方法对35例肺部疾病患者进行64层CT支气管动脉成像,以VR、MIP及MPR后处理技术显示支气管动脉解剖学特征。结果 35例患者中,共63支支气管动脉获得显示,右侧39支,左侧24支;支气管动脉正常起源34例,异常起源1例;4例有肺外体循环动脉参与供血,共10支血管,1例存在异常体循环动脉供血。最常见的支气管动脉类型为R1L1型（18/35）。27例支气管动脉增粗,直径2~5 mm。结论 64层CTA支气管动脉成像可无创、直观显示支气管动脉及肺外体循环动脉的形态解剖学特征。Objective To investigate the value of 64-slice CT angiography （CTA） in displaying three dimensional anatom- ic structures of bronchial arteries. Methods Totally 35 patients with lung diseases underwent 64-slice CTA to demonstrate anatomic structures of bronchial arteries with VR, MIP and MPR post-processing technique. Results In 35 patients, 63 bronchial arteries were identified （39 on the right and 24 on the left）, among which bronchial arteries of 34 patients had normal origin and 1 had ectopic origin. Altogether 10 bronchial arteries took part in nonbronchial systemic arteries in 4 pa- tients, and 1 patient had abnormal systemic artery. The common type of the bronchial arteries was RILl （18/35）. Bron chial arteries dilatation was seen in 27 of 35 patients, with diameter of 2--5 mm. Conclusion 64-slice CTA of bronchial ar tery can reveal the morphological anatomic characteristics of bronchial arteries and nonbronchial systemic arteries non-inva sively and directly.
