As a consequence of recent studies that have (1) established the role for ventilation-perfusion lung scanning in the diagnosis of pulmonary embolism, (2) clarified the contribution of clinical assessment to the diagnostic utility of lung scans, and (3) established a role for the noninvasive assessment of the lower extremities for deep venous thrombosis in patients suspected of having pulmonary embolism, we can now manage clinically stable patients suspected of pulmonary embolism without need for invasive diagnostic procedures. The various studies establishing this approach are reviewed, and an algorithm is presented that allows for the noninvasive workup of clinically stable patients suspected of having pulmonary embolism.
（1）确立了通气-灌注肺扫描在肺栓塞诊断中的作用；（2）阐明了临床评估对肺扫描诊断效用的贡献；（3）确立了对疑似肺栓塞患者下肢深静脉血栓形成进行无创评估的作用，我们现在可以对临床稳定的疑似肺栓塞患者进行管理，而无需进行侵入性诊断程序。本文回顾了确立这种方法的各项研究，并提出了一种算法，可用于对临床稳定的疑似肺栓塞患者进行无创检查。
