Digital subtraction bronchography with stable xenon.
An experimental animal study using digital subtraction fluoroscopy to image the bronchial tree with stable xenon shows that major bronchi can be imaged. A fast frame rate is necessary to minimize the effects of subject motion. Optimum contrast between air in lung and xenon in bronchi is obtained when the first two-thirds of a vital capacity breathhold consists of air or oxygen and the last one-third consists of 100% xenon.
