目的 :探讨核素肺灌注显像定量预测肺癌术后肺功能的临床意义。方法 :将 2 1例肺癌患者按手术方式分为全肺切除组和肺叶切除组 ,肺灌注显像结合常规肺功能检查 ,比较第 1秒用力呼气量 (FEV1)术前预测值与术后实测值的相关关系。结果 :使用该方法定量预测术后肺功能 ,FEV1术前预测值与术后实测值呈显著正相关。2 1例患者均痊愈出院 ,随访无一例有肺功能不全。结论 :核素肺灌注显像定量预测肺癌术后肺功能 ,可作为评估肺癌手术安全性的可靠指标。
Objective: To explore the clinical significance of quantitative lung cancer lung perfusion imaging in the prediction of lung function after lung cancer surgery. Methods: Twenty-one patients with lung cancer were divided into pneumonectomy group and lobectomy group by surgery. Pulmonary perfusion imaging was combined with routine pulmonary function tests to compare the preoperative predictive value of forced expiratory volume (FEV1) and postoperative 1 second. The correlation of measured values. Results: Using this method to quantitatively predict postoperative pulmonary function, the preoperative predictive value of FEV1 was positively correlated with the postoperative value. All 21 patients were discharged from the hospital and none of them had pulmonary insufficiency. Conclusion :The radionuclide pulmonary perfusion imaging is a reliable predictor of lung cancer surgery safety.
