摘要/Abstract

摘要： 目的判定肺灌注断层显像(SPECT肺灌注显像)对肺血栓栓塞症(PE)的诊断价值.方法对227例明确诊断为PE的患者在进行肺平面通气显像的同时,进行了SPECT肺灌注显像和肺平面灌注显像,并与CT肺动脉造影(CTPA)结果进行对比分析.结果在227例PE患者中,平面肺灌注显像阳性者203例,检出率为89.4%.SPECT肺灌注显像阳性者223例,检出率为98.2%.平面肺灌注显像与SPECT肺灌注显像对PE的检出率差异有统计学意义(P<0.01).在221例有CTPA诊断结果的患者中,CTPA显示受累肺段为976个,平面肺灌注显像显示796个肺段阳性,两者符合率为81.6%;SPECT肺灌注显像显示937个肺段阳性,SPECT肺灌注显像与CTPA的符合率为96%;两符合率之间差异有统计学意义(P<0.01).结论 SPECT肺灌注显像能明显提高对PE的诊断价值,可取代肺平面灌注显像,成为诊断PE的常规检查方法.

Abstract: Objective To evaluate the value of SPECT imaging in the diagnosis of pulmonary embolism(PE).Methods SPECT and planar pulmonary perfusion imagings were done in 519 patients with first episode of PE.The results were compared with those of spiral CT pulmonary arteriography(CTPA).Results Among the total 227 patients with planar pulmonary and SPECT imagings,the detection rates of PE was 89.4%(203) and 98.2%(223) respectively.There was significant difference between planar pulmonary and SPECT imaging in detection rate(P<0.01).Among the 221 patients with CTPA results,the abnormal segments detected by CPTA were 976,and by planar pulmonary imaging 796;the coincident rate was 81.6%.In the SPECT imagings,937 abnormal segments were detected,with a 96% coincident rate.Detection rate also differed significantly.Conclusion SPECT imaging improves the performance of diagnosis of PE significantly,it can take place of planar pulmonary imaging and become the routine in the diagnosis of PE.
