摘　　要：目的探讨随即法V/Q显像诊断肺动脉栓塞的临床价值。方法分别随机选择103例和107例可疑肺动脉栓塞患者,分别行随即法V/Q显像(通气显像结束后立即行血流灌注显像)和间隔法V/Q显像(上下午分别行通气和灌注显像或隔日行通气和灌注显像),比较两种方法的诊断肺动脉栓塞灵敏度和特异性的差异。结果随即法V/Q显像和间隔法V/Q显像诊断肺动脉栓塞灵敏度和特异性分别为96.70%、94.79%(P>0.05)和75.00%、72.72%(P>0.05)。结论随即法V/Q显像和间隔法V/Q显像诊断肺动脉栓塞的临床价值无统计学差异,随即法V/Q显像可明显缩短就诊时间,对急性肺动脉栓塞的诊断具有重要意义,但用药量偏大。Objective To investigate the clinical value of lung ventilation/perfusion(V/Q) imaging successively in diagnosis of pulmonary embolism(PE).Methods 103 and 107 patients random selected with suspected PE underwent V/Q imaging in successive(the perfusion imaging was performed after the ventilation imaging immediately) and distance(the ventilation and perfusion imaging was performed independently in the morning and afternoon or during tow days immediately) method respectively.The differences in sensitivity and specificity were compared in the diagnosis of PE.Results The sensitivity and specificity were 96.70%,94.79%(P>0.05)with successive method and 75.00%,72.72%(P>0.05)with distance method.Conclusions There's no obvious difference in diagnosis of PE using successive and distance V/Q imaging.Advantage:The successive V/Q imaging could decurtate the visit time obviously,which is much more important for the diagnosis of acute PE.Shortage:The successive method requested major drug consumption.
