摘　　要：目的探讨并分析多层螺旋CT肺动脉成像在临床肺动脉栓塞诊断中的价值。方法选取2012年6月-2015年6月在我院检查的肺动脉栓塞患者85例,将行多层螺旋CT肺动脉成像诊断的43例患者作为观察组,将行MRI血管造影诊断的42例患者作为对照组,并对两组的诊断情况、图像质量、扫描时间进行观察比较。结果观察组诊断结果的特异性(79.07%)、准确性(93.02%)、敏感性(82.50%)、图像质量等级评分(4.80±1.00)分均高于对照组的特异性(52.38%)、准确性(61.94%)、敏感性(54.76%)、图像质量等级评分(2.30±0.50)分;观察组的扫描时间(6.60±2.00)s低于对照组的(580.00±150.00)s,差异具有统计学意义(P<0.05)。结论多层螺旋CT肺动脉成像的图像质量较高,能够更加准确的对肺动脉栓塞做出判断,同时扫描时间也大大地缩减了。Objective To investigate and analyze the value of multi-slice spiral CT pulmonary angiography in the diagnosis of pulmonary embolism.Methods A total of June 2012 and 2015 June in 85 cases of our hospital for examination of the patients with pulmonary embolism underwent multi-slice spiral CT pulmonary angiography in the diagnosis of 43 patients as the observation group, the MRI angiography in the diagnosis of 42 patients as control group, and the two groups of diagnosis, image quality, scanning time dose were observed and compared.Results Observation group diagnosis specificity （79.07%） and accuracy （93.02%）, sensitivity （82.5%）, image quality rating （4.80 ±1.00） points were higher than those of the control group specificity （52.38%） and accuracy （61.94%）, sensitivity （54.76%）, image quality rating （2.30±0.50） points; The scanning time（6.60±2.00）s in the observation group was lower than that in the control group （580.00±150.00）s, and the difference was statistically significant （P〈0.05）.Conclusion The image quality of multi-slice spiral CT pulmonary artery angiography is higher, it can be more accurate to judge the pulmonary embolism, and at the same time, the scan time is greatly reduced.
