The accurate diagnosis of acute pulmonary embolism often represents a challenge to clinicians. The ventilation/perfusion (V/Q) lung scan provides a safe, noninvasive technique, which has been widely used in the diagnosis of pulmonary embolism. Although some controversy still exists in the management of patients with suspected pulmonary embolism, diagnostic strategies for investigating patients have incorporated V/Q scanning, noninvasive venous studies of the lower extremities and clinical assessment of the likelihood of pulmonary embolism. The combination of these strategies will provide acceptable diagnostic accuracy for evaluating patients with suspected pulmonary embolism in the majority of cases.
急性肺栓塞的准确诊断对临床医生来说常常是一项挑战。通气/灌注（V/Q）肺扫描提供了一种安全、无创的技术，已广泛应用于肺栓塞的诊断。尽管在疑似肺栓塞患者的管理方面仍存在一些争议，但对患者进行检查的诊断策略已纳入V/Q扫描、下肢无创静脉检查以及肺栓塞可能性的临床评估。这些策略的结合将在大多数情况下为评估疑似肺栓塞患者提供可接受的诊断准确性。
