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 investigate the value of spiral CT pulmonary angiography (SCTPA) and radionuclide pulmonary ventilation / perfusion (V / Q) scan in the diagnosis of acute pulmonary thromboembolism (PTE). Methods From January 2003 to December 2006, 92 patients with suspected acute PTE in Respiratory Department of Qingdao Municipal Hospital were investigated for SCTPA, radionuclide V / Q scan and related examinations. The SCTPA, pulmonary V / Q scan and combined examination of PTE Diagnostic value. Results Of the 92 suspected PTE patients, 35 were diagnosed as pulmonary embolism. The area under the receiver operating characteristic (ROC) curve of subjects with SCTPA was 0.922, the area under the ROC curve of pulmonary V / Q scan was 0.824, and the area under the ROC curve of the joint examination was 0.933, significantly higher than that of lung V / Q scan (Z = 2.05, P <0.05). Conclusion SCTPA combined with pulmonary V / Q scan can improve the diagnostic efficiency of acute PTE.
