Abstract
A diagnostric device, composition and method of diagnosing airway dysfunction in a patient is disclosed. The apparatus and method require the subjecting of a pharmaceutical acceptable radionuclide, that is the composition, to an elevated temperature in an enclosed space in the presence of either an inert gas or oxygen to produce an inhalable product. The product is inhaled by a patient. A film is located adjacent the airways enabling mapping of the deposition of the radionuclide in the airways of the patient's lungs.
