The potentialities of pneumoscintigraphy (its perfusion and inhalation variants) were estimated to assess the state of the broncho-vascular system in 35 patients, subjected to radiotherapy for lung cancer. It was found that nearly all patients with bronchial cancer showed an impairment of the perfusion and ventilation which was dependent on tumor localization and the degree of its local-regional proliferation. Studies on the pulmonary blood flow and ventilation in these patients during radiation treatment have demonstrated in most of them restoration of the involved bronchus drainage function, while in a half of the patients, in whom some regression of the tumor process was revealed roentgenologically, no improvement of the perfusion was noted. Also, it is stated that perfusion scanning is of great importance in estimating the efficacy of radiotherapy for regional metastases.
对35例接受肺癌放疗的患者进行肺闪烁造影（灌注和吸入两种方式），以评估其支气管血管系统的状况。结果发现，几乎所有支气管癌患者的灌注和通气功能均有损害，这取决于肿瘤的位置及其局部区域增殖程度。对这些患者放疗期间肺血流和通气的研究表明，大多数患者受累支气管的引流功能得以恢复，而在其中一半经X线检查显示肿瘤有一定消退的患者中，未观察到灌注改善。此外，研究表明灌注扫描在评估区域转移放疗疗效方面具有重要意义。
