We investigated preliminary the clinical utility of dynamic SPECT in studying pulmonary Xenon-133 gas washout, using the continuous repetitive rotating acquisition method with a triple-headed SPECT system. The subjects included one healthy volunteer and 16 various lung diseases. After obtaining the equilibrium images, the sequential washout images were acquired every 60 sec for 6 min. As the ventilation index, the real half-time of regional activity was evaluated. With or without abnormalities on chest CT, these images allowed us to show effectively the three-dimensional distribution of ventilation abnormalities, such as peripheral or segmental air trapping.
我们使用三头单光子发射计算机断层扫描（SPECT）系统的连续重复旋转采集方法，初步研究了动态SPECT在研究肺内氙-133气体洗脱中的临床应用。研究对象包括1名健康志愿者和16例患有各种肺部疾病的患者。在获得平衡图像后，每隔60秒采集一次连续洗脱图像，共采集6分钟。作为通气指标，评估区域活性的实际半衰期。无论胸部CT有无异常，这些图像都能有效地显示通气异常的三维分布，如外周或节段性气体潴留。
