64层螺旋CT血管造影诊断中度疑似肺栓塞的临床价值

目的探讨肺通气灌注显像和CT肺动脉造影2种无创性检查技术诊断肺栓塞（PE）,对临床Wells评分分组为中度疑似肺栓塞的诊断价值。方法 将2006年3月至2009年11月,临床Wells评分分组为中度疑似肺栓塞60例患者,行64层螺旋CT肺动脉造影和肺通气/灌注显像,对2种显像的判定结果进行相关分析,其准确性、符合性及不确定性诊断比率的差异采用χ2检验进行比较。结果 Wells评分为中度可能组中CTPA和V/Q显像诊断PE的敏感性、特异性、符合率分别为：88%、72%、P〈0.01;91%、77%、P〈0.01;90%、74%、P〈0.01。结论在Wells评分中度可能性组别中,CTPA诊断PE均较V/Q显像的价值高,并可作为临床中度疑诊肺栓塞病例的首选检查方法。
