目的：探讨COPD患者通气血流灌注（V／Q）扫描结果与肺功能的关系。方法：30例COPD患者V／Q扫描的结果与肺功能测定结果，按损害的严重程度进行比较。结果：COPD患者V／Q扫描结果与肺功能损害的严重程度无显著差异，可以反映肺功能的损害程度。结论：由于V／Q扫描相对肺功能测定较省力，病人容易配合，所以严重肺功能受损难以配合肺功能检查的病人可以作V／Q扫描估测肺功能的状况。 Objective: To investigate the relationship between pulmonary ventilation and ventilation perfusion (V / Q) in COPD patients. Methods: The results of V / Q scan in 30 patients with COPD were compared with those of lung function test according to the severity of the damage. Results: There was no significant difference between the V / Q scan results and the severity of pulmonary dysfunction in COPD patients, which could reflect the degree of lung function damage. CONCLUSIONS: Because V / Q scan is less labor-intensive than pulmonary function tests and patients are easy to mate, patients with severe pulmonary impairment who are not eligible for pulmonary function tests can be assessed V / Q scan for lung function status.
