Radioxenon ventilation studies with disposable apparatus: technique and application.
Modification of commercially supplied disposable apparatus for radioxenon ventilation imaging solved several problems: occasional poor inhalation of the initial bolus of gas, awkward initiation of the wash-out phase, and building up of pressure against which the patient must exhale in the wash-out phase. Two cases illustrate results of ventilation and perfusion imaging in chronic obstructive pulmonary disease and pulmonary embolism. A third case illustrates results before and after bullectomy, including quantitative data analysis of the wash-out phase. Although long-range economy is possible with permanent equipment, the use of the modified disposable apparatus may be preferable in certain circumstances.
