摘　　要：目的探讨核素定量肺显像在预测肺切除术后肺功能中的作用。方法运用９９ｍＴｃ－ＭＡＡ进行肺灌注显像及９９ｍＴｃ－ＤＴＰＡ进行肺通气显像，经计算机处理测出左右肺灌注、通气百分比，结合常规肺功能检查算出术后肺功能，再与术后实测值比较。结果发现二者间密切正相关；同时，灌注显像还可对肺癌切除可能性作出估计，当患侧肺灌注量小于总量的３０％时肺癌切除可能性很小。结论该方法可靠、易行，且具有一定的临床意义。Objective To explore the effects of radionuclide lung scanning in the prediction of postoperative pulmonary function and estimation of the resection probability of lung cancer. Methods 99m Tc MAA pulmonary perfusion scanning and 99m Tc DTPA pulmonary ventilation scanning were performed preoperatively on patients with lung cancer. Both scannings were computerized to tell the pulmonary perfusion on each side and ventilation percentage. Then we calculate the predicted value of postoperative pulmonary function by combining the ventilation percentage with the spirometric value. Comparison of the predicted value with the postresection actual one was alsomale. Results We fonud that the predicted value was well correlated to the actual value. Meanwhile, the perfusion scanning can be used to estimate the probability of tumour resection if the perfusion percentage of the lung with tumor is lower than 30 percentage of the total perfusion, the tumour resection rate is only 40 percent. Conclusion The results suggest that this method is simple and accurate, and has some clinical importance.
