摘　　要：目的探讨螺旋CT肺血管成像(SCTPA)联合核素肺通气/灌注(V/Q)扫描检查在急性肺动脉血栓栓塞(PTE)诊断中的应用价值。方法对2003年1月至2006年12月青岛市立医院呼吸科92例疑似急性PTE患者进行SCTPA、核素肺V/Q扫描以及相关检查,评价SCTPA、肺V/Q扫描以及联合检查对PTE的诊断价值。结果92例疑似PTE患者中,确诊肺栓塞者35例。SCTPA的受试者工作特征(ROC)曲线下面积为0.922,肺V/Q扫描的ROC曲线下面积为0.824,联合检查的ROC曲线下面积为0.933,明显高于肺V/Q扫描(Z=2.05,P<0.05)。结论SCTPA联合肺V/Q扫描可提高对急性PTE的诊断效率。Objective To evaluate the clinical value of SCTPA and pulmonary V/Q scan in the diagnosis of pulmonary thromboembolism （PTE）. Methods Ninety-two patients suspected of having PTE received SCTPA, pulmonary V/Q scan, and other related examinations. Results Thirty-five patients were diagnosed as having PTE in 92 patients investigated,30 cases were revealed by SCTPA, and 20 cases revealed by pulmonary V/Q scan. The area under ROC curve of SCTPA by V/Q scan and combination examination was 0. 922, 0. 824, and 0. 933, respectively （ P 〈 0. 05 ）. Conclusion SCTPA combined with V/Q scan can improve the accuracy of diagnosis.
