摘　　要：目的分析单光子发射计算机断层及X射线计算机体层摄影成像系统(SPECT/CT)肺灌注显像对肺栓塞的诊断价值。方法纳入2019年3月至2022年3月开封市中心医院收治的80例疑似肺栓塞患者为研究对象,进行前瞻性研究,对所有患者实施SPECT/CT肺灌注显像检查,以肺动脉造影检查结果为金标准,分析SPECT/CT肺灌注显像对肺栓塞的诊断效能及对肺栓塞类型的评估价值。结果80例疑似肺栓塞患者中肺栓塞71例(88.75%),非肺栓塞9例(11.25%)。以肺动脉造影检查结果为金标准,SPECT/CT肺灌注显像诊断肺栓塞的灵敏度、特异度、准确度、阳性预测值、阴性预测值分别为90.14%(64/71)、88.89%(8/9)、90.00%(72/80)、98.46%(64/65)、53.33%(8/15);SPECT/CT肺灌注显像评估肺栓塞类型与肺动脉造影检查结果的一致性极好(Kappa=0.852,P<0.05)。结论SPECT/CT肺灌注显像对肺栓塞具有良好诊断价值,可准确评估肺栓塞类型。Objective To analyze the diagnostic value of single photon emission computed tomography and X-ray computed tomography(SPECT/CT)pulmonary perfusion imaging for pulmonary embolism.Methods A total of 80 patients with suspected pulmonary embolism treated in Kaifeng Central Hospital from March 2019 to March 2022 were enrolled the study as research objects.SPECT/CT pulmonary perfusion imaging was performed on all patients.And the results of pulmonary angiography were taken as the gold standard,to analyze diagnostic efficacy of SPECT/CT pulmonary perfusion imaging for pulmonary embolism and its value in evaluating the type of pulmonary embolism.Results Among the 80 patients with suspected pulmonary embolism,71 cases(88.75%)had pulmonary embolism and 9 cases(11.25%)had non pulmonary embolism.With results of pulmonary angiography as the gold standard,the sensitivity,specificity,accuracy,positive predictive value and negative predictive value of SPECT/CT pulmonary perfusion imaging in diagnosing pulmonary embolism were 90.14%(64/71),88.89%(8/9),90.00%(72/80),98.46%(64/65)and 53.33%(8/15),respectively.The consistency between SPECT/CT pulmonary perfusion imaging and pulmonary angiography was excellent(Kappa=0.852,P<0.05)in evaluation of pulmonary embolism type.Conclusions SPECT/CT pulmonary perfusion imaging has good diagnostic value for pulmonary embolism,and it can accurately evaluate the type of pulmonary embolism.
