With either electrodiagnostic criterion, the majority of the large changes in probability were for patients for whom the pretest probability was 0.50.
无论采用哪种诊断标准，患病率的变化较大的主要是检查患病率0.50的患者。
In patients with a moderate or high pretest probability, these findings are associated with a greater than 85% post-test probability of pulmonary embolism.
如果患者具有中度或高度的肺栓塞验前概率，那么其验后概率将高于85%。
Recent systematic reviews indicate that CT alone may not be sufficiently sensitive to exclude pulmonary embolism in patients who have a high pretest probability of pulmonary embolism.
最近系统性回顾表明对那些有高预发性肺栓塞的病人单独使用CT可能不足以排除患肺栓塞的可能。
