目的分析64层螺旋CT血管成像(MSCTA)在肺血管病变中的临床诊断价值。资料与方法对42例临床拟诊肺血管病变的患者行MSCTA,对所有图像行容积再现(VR)、多平面重组(MPR)、最大密度投影(MIP)。结果42例有肺血管病变,其中3例确诊为肺动静脉瘘,可以显示扩张迂曲的肺动脉和引流的肺静脉;6例确诊为肺动脉瘤,可以显示局限扩张的肺动脉;9例确诊为肺隔离症,可以显示异常体循环供血血管;24例确诊为肺动脉栓塞(PE),主要表现为肺动脉管腔内偏心性和附壁性充盈缺损。结论MSCTA可以无创地诊断肺动静脉瘘、肺动脉瘤、肺隔离症及PE,可为肺部血管性疾病的诊断与治疗提供重要依据。
Objective To analyze the clinical value of 64-slice spiral CT angiography (MSCTA) in the diagnosis of pulmonary vascular disease. Materials and Methods 42 cases of clinically diagnosed pulmonary vascular disease were treated with MSCTA, volume rendering (VR), multiplanar reconstruction (MPR) and maximum density projection (MIP). Results 42 cases of pulmonary vascular disease, of which 3 cases were diagnosed as pulmonary arteriovenous fistula, showing the expansion of the tortuous pulmonary artery and drainage of the pulmonary veins; 6 cases diagnosed as pulmonary aneurysms, can show the limitations of expansion of the pulmonary artery; 9 cases diagnosed as pulmonary sequestration , Can show abnormal systemic circulation of blood vessels; 24 cases were diagnosed as pulmonary embolism (PE), mainly manifested as pulmonary artery luminal eccentricity and adherent filling defect. Conclusion MSCTA can diagnose pulmonary arteriovenous fistula, pulmonary aneurysm, pulmonary sequestration and PE noninvasively, which may provide an important basis for the diagnosis and treatment of pulmonary vascular diseases.
