Summary
Asthma is a disease of rapidly increasing incidence that already affects more than 17 million
people in the United States alone. It has long been known that areas of severely reduced
airflow occur in asthma and contribute significantly to the impairment of gas exchange in
this disease. However, the extent to which local blood flow changes during an asthmatic
attack is unclear. The purpose of this study is using Positron Emission Tomography - Computed
Tomography imaging to evaluate how the blood flow changes in the lungs during an asthma
attack induced by allergens.
