1、64排螺旋CT扫描对肺栓塞诊断价值研究 [摘要]目的评价64排螺旋CT肺动脉血管造影(CTPA)对肺栓塞(PE)的诊断价值。方法对临床疑诊急性PE的72例患者进行CTPA检查,并进行多平面重建(MPR)、最大密度投影(MIP)及容积重建技术(VR)。结果72例患者中确诊为PE患者29例,共累及476处肺动脉及分支,其中,右肺动脉主干36处,左肺动脉主干42处,肺叶动脉157处,肺段动脉203处,亚段动脉38处。CTPA征象分为直接和间接征象,直接征象:肺动脉主干或分支内混合性、附壁性、中心性充盈缺损;间接征象:局限性肺纹理稀疏,肺动脉高压,右心室增大,胸腔积液等。结论64排CT
2、PA具有准确、快速、无创伤等优点,可立体、直观地观察到肺动脉血栓的大小、分布及范围,并可观察患者的肺内间接改变,是临床诊断及观察疗效的首选方法。[关键词]64排螺旋CT;肺栓塞;诊断价值[中图分类号]R445.3[文献标识码]B[文章编号]1674-4721(2013)07(a)-0093-02Thevalueofthe64rowspiralCTscaninthediagnosisofpulmonaryembolismYEZhen-zhong1WANGQing-shan1CHENLi-jun1LIZhi-zhao2HEWei1CHENShi-hong181.Departmento
