【摘要】 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。更多还原

【Abstract】 Objective To evaluate clinical value of the 64 slice CT angiography in the diagnosis of pulmonary vascular disease.Materials and Methods 42 cases of suspected pulmonary vascular disease received 64 slice CT using volume rendering(VR),multi-plane projection(MPR),maximum intensity projection(MIP).Results There were 42 cases of patients with pulmonary vascular disease in 82 cases,3 patients were diagnosed with pulmonary arteriovenous fistula with tortuous expanding pulmonary artery and draining pulmonary vein;6 patients were diagnosed with pulmonary artery aneurysm with local expansion of the pulmonary artery;9 cases were confirmed as pulmonary sequestration with abnormal systemic blood vessels;24 patients were diagnosed with pulmonary embolism with filling defect of the eccentric and mural in the pulmonary artery lumen.Conclusion 64-slice CT angiography is a non-invasive method to diagnose pulmonary arteriovenous fistula,pulmonary aneurysm,pulmonary sequestration and pulmonary embolism,which is important for diagnosis and treatment.更多还原
