Abstract
Functional maps of local pulmonary ventilation are derived from serial computed tomographic images acquired prior to and during a short period of inhalation of subanesthetic xenon/oxygen gas mixtures. Preliminary results from human studies yield quantitative maps of local ventilation rates with excellent anatomic specificity demonstrating nonuniformities in the distribution of ventilation in normal and abnormal human lungs.
摘要
局部肺通气功能图是从在吸入亚麻醉剂量氙/氧气混合气体之前及吸入短时间内所获取的系列计算机断层扫描图像得出的。人体研究的初步结果得出了局部通气率的定量图，具有出色的解剖特异性，显示了正常和异常人体肺部通气分布的不均匀性。
