肺通气/灌注与CT肺动脉造影诊断肺栓塞对比分析

Comparison of clinical value of lung ventilation/perfusion and CT pulmonary angiography

目的:探讨肺通气/灌注(V/Q)显像与CT肺动脉造影(CTPA)在肺栓塞诊断中的应用价值。方法:选择我院2006年4月～2010年4月收治的肺栓塞患者164例,按照疾病程度分为大面积肺栓塞组(48例)、次大面积肺栓塞组(56例)和非大面积肺栓塞组(60例)3组,对3组患者V/Q显像与CTPA检出率进行比较。结果:肺V/Q显像总检出率为91.46%,CTPA总检出率为90.24%,2种方法总检出率差异无统计学意义(P>0.05)。不同方法对A、B、C组阳性检出率不同,A组CTPA检出率明显高于肺V/Q显像,B、C组V/Q显像检出率明显高于CTPA,差异均有统计学意义(t分别为5.83、5.02、5.13,P均<0.05)。结论:肺V/Q显像与CTPA诊断栓塞各有优缺点,临床中根据患者情况结合应用,为治疗提供准确有效的信息。

Objective： Objective To discuss the value of pulmonary ventilation / perfusion（V / Q） imaging and CT pulmonary angiography（CTPA） in the pulmonary embolism diagnosis.Methods：A total of 164 cases with pulmonary embolism admitted from April 2006 to April 2010 were selected.They were divided into three groups： large area pulmonary embolism group（48 cases）,the second largest area group（56 cases） and non-massive pulmonary embolism group（60 cases） in accordance with the disease degree.The detection rates of V / Q imaging and CTPA were observed and compared.Results：The detection rate of V / Q imaging was 91.46%,CTPA detection rate was 90.24%,and there was no significant difference between two methods（P0.05）.The detection rate of CTPA was significantly higher than V / Q imaging in group A,while the rate of V / Q imaging was significantly higher in group B and C（t=5.83,5.02,5.13,allP0.05）.Conclusion：V / Q imaging and CTPA have their own advantages and disadvantages in clinical application.They should be applied depending on the patient＇s condition,in order to play better in the clinical using.
