摘　　要：目的:探讨多层螺旋CT肺动脉血管成像(MSCTPA)诊断肺血管病变的临床价值。方法:回顾性分析经手术病理或DSA证实的41例肺血管病变的MSCTPA影像表现,图像后处理包括容积再现(VR)、薄层最大密度投影(thin-MIP)、多平面重组(MPR)。结果:全部病例依据直观的二维、三维重组图像得以明确诊断,其中获得性肺血管病21例,包括肺动脉栓塞19例,肺动脉瘤2例;先天性肺血管病20例,包括肺动静脉瘘14例,肺隔离症3例,动脉导管未闭并发肺动脉瘤1例,部分性肺静脉畸形引流2例。结论:MSCTPA结合二维、三维图像重组技术能全面、直观地显示病变全貌,对肺血管病变的临床诊断和治疗有重要价值,可取代有创的DSA检查。Objective：To explore the clinical value of multi-slice spiral CT pulmonary angiography（MSCTPA） in the diagnosis of pulmonary vascular disease（PVD）.Methods：The imaging manifestations of MSCTPA in 41 cases with pulmonary vascular diseases proved by pathology or DSA were analyzed retrospectively.Image post-processing included volume rendering（VR）,thin-maximum intensity projection（thin-MIP） and multiple planar reconstruction（MPR）.Results：All patients were accurately diagnosed based on images of two and three-dimensional（2D,3D） reconstruction.Of them 21 cases were acquired PVD,including pulmonary artery embolism 19 cases and pulmonary aneurysm 2 cases,and 20 cases were congenital PVD,including pulmonary arteriovenous malformation（PAVM） 14 cases,pulmonary sequestration 3 cases,patent ductus arteriosus（PDA） complicated with pulmonary aneurysm 1 case and partial pulmonary venous abnormal drainage 2 cases.Conclusion：Combined application of MSCTPA and 2D,3D reconstruction can fully display the lesions directly,being of great significance for clinical diagnosis and treatment of pulmonary vascular diseases.It can replace the invasive DSA.
