在怀疑肺栓塞102例患者中,我们评价了放射性核素静脉造影与肺灌注扫描相结合以确立肺栓塞诊断的可能性。因为肺栓塞与腿部深部静脉血栓形成有关系。用一个特定的模型和Bayes的理论来比较单独用肺灌注扫描和结合放射性核素腿部静脉造影的诊断效果,即比较了两种诊断标准:标准一:肺灌注扫描图显示肺栓塞高度可能性,但不能肯定;标准二:肺灌注扫描图显示肺栓塞高度可能,且放射性核素腿部静
In 102 suspected pulmonary embolism patients, we evaluated the possibility of radionuclide venography combined with lung perfusion scan to establish the diagnosis of pulmonary embolism. Because of pulmonary embolism and leg deep venous thrombosis are related. Using a specific model and Bayesian theory to compare the diagnostic efficacy of pulmonary perfusion alone with radionuclide leg venography, two diagnostic criteria were compared: Standard one: Lung perfusion scan shows a high probability of pulmonary embolism , But not sure; standard two: lung perfusion scan showed a high degree of possible pulmonary embolism, and radionuclide leg static
