摘要
目的用放射性核素肺显像预测肺切除术后的肺功能。方法２５例均经手术、病理证实的患者中，原发性肺癌１８例，转移性肺癌１例，肺良性病变６例。通过１９例肺部手术患者术前１秒钟用力呼气容积预测值与手术后１个月和１年的实测值进行对比分析。结果放射性核素肺灌注显像法预测值与术后１个月和１年实测值均显著相关，ｒ分别为０９７１８、０９８８９，Ｐ均＜００１。放射性核素肺通气显像法预测值与术后１个月和１年实测值也显著相关，ｒ分别为０９７３９、０９７９３，Ｐ均＜００１。灌注显像与通气显像所得结果一致。
Purpose To predict the postoperative pulmonary function using radionuclide lung imaging before pneumonectomy Methods The study was performed with 99m Tc macroaggregated (MAA) pulmonary perfusion imaging and 99m Tc DTPA ventilation imaging in 19 patients before pneumonectomy The predicted forced expiratory volume in one second values were compared with measured values in 1 month and 1 year after surgery respectively Results The predicted values well correlated with the measured values in 1 month and 1 year after surgery with pulmonary radionuclide perfusion imaging (r=0 971 8, P<0 01 and r=0 988 9, P<0 01) And with radionuclide lung ventilation imaging the predicted values were also correlated with measured values in 1 month or 1 year after surgery (r=0 973 9, P<0 01 and r=0 979 3, P<0 01) Conclusions Either pulmonary radionuclide perfusion imaging or ventilation imaging can provide a simple non invasive and accurate method for the preoperative functional evaluation of the high risk patients
