Abstract:Objective To investigate the function and effectiveness of the high-power atomizer in
producing aerosol contrast agent so as to find the method for the diagnosis of respiratory diseases in
early stages. Methods The high-power atomizer was adopted to atomize the X-ray contrast agent into
aerosol contrast agent. Then aerosol contrast imaging was produced in human lungs and pig lungs.
The specific methods are listed as the following steps: the subject actively inhaled the aerosol contrast
agent into airways through oropharynx; a chest film was after the subject breathed in deeply, slowly,
and repeatedly; the spraying aerosol contrast agent was continuously and directly shot into the airways
of pig lung specimens; then imaging was produced. Results The human chest films clearly show
parts of proximal airway images without causing any irritation to the airway, whereas the film of pig
lung specimens show clear images from trachea, bronchus and bronchioles, to pulmonary alveoli.
Conclusion Each section of the bronchus images of the passively-sprayed pig lung specimens can meet
the diagnostic demands and provide accurate location of lesion for clinical treatment. Although part of
the pulmonary airway forms images produced after patient inhales aerosol contrast agent, but it cannot
meet the diagnostic demands. By increasing the aerosol amount, the imaging can be clearer to meet the
diagnostic standards.
