摘　　要：目的:探讨肺通气/灌注(V/P)比值显像在肺血栓栓塞症(PTE)诊断中的价值。方法:对10例临床确诊的PTE患者V/P显像,并行定量分析。结果:10例患者共43个肺段经临床确认为肺血栓栓塞,常规目测读片诊断肺血栓栓塞46个,其中符合临床37个,灵敏度86.05%,特异性93.43%。V/P比值显像诊断肺血栓栓塞41个,与临床符合39个,灵敏度90.70%,特异性98.54%。结论:V/P比值显像可明显提高特异性。Objective：To discuss the value of the pulmonary ventilation/perfusion ratio imaging in diagnosis of pulmonary thromboembolism（PTE）. Methods ：Ten patients underwent radionuclide pulmonary ventilation/perfusion imaging and quantitative analysis. Results ： Fouty-three pulmonary segments diagnosed as with PE by clinic and pulmonary angiography. 46 pulmonary segments diagnosed as with PTE by general eyeballing,the sensitivity is 86. 04%, the specificity is 93. 43%. 41 pulmonary segments diagnosed as with PTE by quantitative analysis,the sensitivity is 90.69%,the specificity is 98.54 %. Conclusion ：Quantitative analysis can increase special.
