摘要
目的:分析CT肺血管造影(CTPA)联合双能量肺灌注成像(DEPI)对老年肺栓塞治疗效果的评估价值。方法:采用回顾性分析本院45例老年肺栓塞患者的临床资料,采用双能量软件获取患者治疗前后CTPA和DEPI图像数据,记录图像特征;比较患者治疗前后扫描剂量和图像质量,分别比较治疗前后CTPA和DEPI图像肺栓塞相关指标的情况。结果:患者治疗前后扫描剂量和图像质量的比较,均差异无统计学意义(P>0.05)。CTPA、DEPI图像中,患者治疗后肺动脉干、肺叶动脉、肺段动脉及亚段肺动脉中栓子数量均明显少于治疗前(P<0.01);CTPA图像中,患者治疗后肺栓塞评分和肺栓塞评分指数均明显低于治疗前(P<0.01);DEPI图像中,患者治疗后肺灌注缺损评分和肺灌注缺损指数均明显低于治疗前(P<0.01)。结论:CTPA可反映老年肺栓塞患者治疗前后栓子变化情况,DEPI可作为CTPA的补充,二者联合可对肺栓塞相关参数进行定量分析,从而更好地评价患者治疗效果。
Objective:To analyze the evaluation value of CT pulmonary angiography(CTPA)combined with dual-energy pulmonary perfusion imaging(DEPI)in the treatment of pulmonary embolism in the elderly.Methods:A retrospective study was conducted to collect the clinical data of 45 elderly patients with pulmonary embolism in our hospital.The image data of CTPA and DEPI before and after treatment were obtained by dual energy software,and the image characteristics were recorded.The scanning dose and image quality of patients before and after treatment were compared,and the related indexes of CTPA and DEPI before and after treatment were compared.Results:There was no significant difference in scanning dose and image quality between before and after treatment(P>0.05).In CTPA and DEPI images,the number of emboli in pulmonary artery trunk,lobar artery,segmental artery and subsegmental pulmonary artery after treatment was significantly less than that before treatment(P<0.01);in CTPA images,the pulmonary embolism score and pulmonary embolism score index after treatment were significantly lower than those before treatment(P<0.01);in DEPI images,the pulmonary perfusion defect score and pulmonary perfusion defect index after treatment were significantly lower than before treatment(P<0.01).Conclusions:CTPA can reflect the changes of embolism in elderly patients with pulmonary embolism before and after treatment.DEPI can be used as a supplement of CTPA.The combination of the two can be used for quantitative analysis of parameters related to pulmonary embolism,so as to better evaluate therapeutic effect.
