Independent, random, and multiple evaluations by three observers of pulmonary perfusion scintiscans with and without ventilation scans demonstrated a 39% reduction in diagnosis of pulmonary embolism when ventilation scans were included. These findings suggest that four of 10 cases diagnosed as having pulmonary emboli on the basis of perfusion imaging procedures alone would have the diagnosis changed.
三位观察者对有通气扫描和无通气扫描的肺灌注闪烁扫描进行独立、随机和多次评估，结果显示，纳入通气扫描后，肺栓塞的诊断率降低了39%。这些发现表明，仅基于灌注成像程序被诊断为患有肺栓塞的10例病例中，有4例的诊断会发生改变。
