目的：评价核素肺通气/灌注( V/Q )显像在肺动脉栓塞( PE )诊断中的价值。方法临床疑有PE患者147例，均行肺通气/灌注( V/Q )显像。结果147例患者中有91例V/Q显像诊断PE ，56例V/Q显像正常或匹配，排除PE。临床最终确诊PE 83例，4例大动脉炎，4例正常。56例V/Q显像正常或匹配者均排除PE。肺V/Q显像对诊断PE的灵敏度、特异性、准确性、阳性预测值和阴性预测值分别为100％(83/83)、87.5％(56/64)、94.6％(139/147)、91.2％(83/91)和100％(56/56)。结论 V/Q显像灵敏度及阴性预测值高，提示其检出疾病的能力强，漏诊率低，且可作为排除PE的首选方法。

Objective To assess the value of pulmonary ventilation-perfusion(V/Q ) im aging in the diagnosis of pulmonaryem bolism (PE ). Methods 147 sufferers with clinically suspected pulmonaryem bolism were given pulmonary ventilation-perfusion im aging .Results Among the 147 sufferers,91 were diagnosed as PE in V/Q im aging.56 of them were excluded PE with norm al or matching V/Q im aging.At last,83 were definitely diagnosed as PE ,4 of them were conform ed as Takayasu's arteritis,and 4 of them were norm al.56 with norm al or matching V/Q im aging were all excluded PE .The sensitivity,specificity,accuracy,positive predictive value,and negative predictive value of PE by ventilation-perfusion im aging were 100%(83/83),87.5%(56/64),94.6%(139/147),91.2%(83/91)and 100%(56/56) respectively.Conclusion The high sensitivity and negative predictive value of V/Q im aging indicates that it has high ability of detecting PE and low rate of m issed diagnosis.V/Q im aging is the first choice for excluding PE .
