摘要：
目的 分析64 排螺旋CT 肺动脉成像技术对肺动脉栓塞进行诊断的临床意义。方法 选取2015 年5 月至2016 年5 月 本院收治的疑似肺动脉栓塞患者40例作为本次的研究对象，为所有患者开展64 排螺旋CT 肺动脉成像技术检查，比较 MPR、MIP 及VR 三种处理方式对各级动脉病灶的检出率。结果 MPR、MIP 及VR 对1 级肺动脉病灶的检出率比较，差异不具 有统计学意义（P>0.05），MPR 对2～3 级肺动脉病灶检出率明显高于MIP 和VR（P<0.05）；MPR 对4～5 级肺动脉病灶检出率 同MIP 及VR 比较，差异无统计学意义（P>0.05）。结论 应用64 排螺旋CT 肺动脉成像技术对肺动脉栓塞进行诊断，结合各种图像后处理方式可提高疾病的检出率，可以早期诊断疾病，为临床治疗提供参考，值得广泛推广。

ABSTRACT: Objective To explore the clinical significance of 64 -slice spiral CT pulmonary artery imaging in the diagnosis of pulmonary embolism. Methods From May 2015 to May 2016, 40 patients with suspected pulmonary embolism were selected as study objects, and they all received spiral CT pulmonary angiography detection, then the detection rates of arterial lesions were compared among MPR, MIP and VR imagings. Results MPR, MIP and VR imagings had no significant difference in the detection rate of grade 1 pulmonary artery lesions (P>0.05). The detection rate of grade 2-3 pulmonary lesions in MPR imaging was significantly higher than that of MIP and VR, the differences were statistically significant (P<0.05). There was no significant difference in the detection rate of grade 4-5 pulmonary artery lesions among MPR, MIP and VR (P>0.05). Conclusion The application of 64-slice spiral CT pulmonary artery imaging combined with a variety of image post-processing methods can effectively increase the detection rate in the diagnosis of pulmonary embolism. It can help diagnose disease early, and provide a reference for clinical treatment, which is worth widely disseminated.
