ABSTRACT
CT-functional images (CT-FI's) were created from Xe-dynamic CT data of 10 patients with chronic pulmonary emphysema and 6 volunteers with normal lung. In CT-FI's of normal lungs, the values of washin and washout parameter of outer zone were larger than those of inner zone. In CT-FI's of chronic pulmonary emphysema, the values of washin parameter of inner zone were larger than those of outer zone and the value of washout parameter of outer zone were larger than those of inner zone. CT-FI's proved to helpful in evaluating the axial distribution of ventilation dynamics in chronic pulmonary emphysema.
