摘要
目的:评价肺通气灌注显像与64排CT肺动脉造影在诊断肺动脉栓塞中的价值。方法:选取73例临床怀疑有肺动脉栓塞的患者,分别进行核素肺通气灌注显像以及64排CT肺动脉造影两种检查,以最终临床确诊为标准,评价并比较两种显像对肺动脉栓塞的诊断价值。结果:核素肺通气灌注显像对肺动脉栓塞诊断的灵敏度、特异度、阳性预测值以及阴性预测值依次为:82.86%、92.11%、90.63%和85.37%。64排CT肺动脉造影检查诊断肺动脉栓塞的灵敏度、特异度、阳性预测值及阴性预测值分别为:89.74%、94.12%、94.59%和88.89%。结论:64排CT肺动脉造影诊断肺动脉栓塞的特异性强,核素肺通气灌注显像诊断肺动脉栓塞的灵敏度较高;二者均为诊断肺动脉栓塞有效的影像学方法,且联合应用有助于更好地诊断肺动脉栓塞。
Objective： To evaluate the value of ventilation-perfusion imagining and 64 slice Spiral CT pulmonary angiography in diagnosis of pulmonary embolism. Methods： To analyze 73 patients clinical suspected pulmonary embolism. All the patients both undertook 64 slice Spiral CT pulmonary angiography and entilation-perfusion imagining. At the end, evaluate separately the diagnosis value of two imaging methods based on final clinical diagnosis. Results： The sensitivity, specificity, accuracy, positive predictive value, negative predictive value of ventilation-perfusion imagining respectively were： 82.86%,92.11%,90.63%,85.37%; and the same indexes of 64 slice Spiral CT pulmonary angiography respectively were： 89.74%,94.12%,94.59%,88.89%. Conclusion： The specificity of 64 slice Spiral CT Pulmonary Angiography is higher than ventilation-perfusion imagining, while the sensitivity of ventilation-perfusion imagining was higher than 64 slice Spiral CT Pulmonary Angiography. And the union application of 64 slice Spiral CT pulmonary angiography and ventilation-perfusion imagining will be better to diagnose pulmonary embolism and both of them are effective and noninvasive imaging methods in diagnosis of pulmonary embolism.
