临床上对慢性阻塞性肺疾病(COPD)患者并发肺栓塞(PE)的诊断比较困难,因为患者在发生PE时的体征及症状往往与COPD出现恶性感染时的体征及症状相互重迭。COPD病人由于活动量减少、年龄老化及心衰,发生PE的危险性增高。由于这些患者的肺活量降低,因而使该病的发病和死亡的危险性增加,因此及时对COPD患者的PE作出明确的诊断是极为重要的。通气/灌注(V/Q)闪烁显像术是一种 Clinical diagnosis of pulmonary embolism (PE) in patients with chronic obstructive pulmonary disease (COPD) is more difficult because the signs and symptoms of PE in patients with PE often overlap with the signs and symptoms of COPD in patients with malignant infections. COPD patients due to reduced activity, age and heart failure, the risk of PE increased. Due to the reduced vital capacity of these patients, the risk of morbidity and mortality from the disease is increased, so it is of paramount importance to have a definitive diagnosis of PE in COPD patients in time. Ventilation / perfusion (V / Q) scintigraphy is one type
