Imaging Airway Liquid Absorption in Cystic Fibrosis
Completed · Not applicable
Conditions studied: Cystic Fibrosis
In brief
The investigators are developing a new nuclear medicine imaging technique for measuring liquid absorption in the airways that can be applied to screen new medications being developed to treat cystic fibrosis (CF). The investigators believe that the absorption of the small molecule radiopharmaceutical Indium 111-diethylenetriaminepentaacetic acid (In-DTPA) will indicate changes in liquid absorption in the airways and demonstrate whether new CF medications will be effective. In this study the investigators will further develop this technique through testing involving pediatric CF patients and healthy control subjects.

- subjects 18 years old or older without a diagnosis of lung disease.
- Pediatric CF arm:
- subjects 6-14 years with a diagnosis of cystic fibrosis as determined by sweat test or genotype
- subjects who are clinically stable as determined by the pediatrician co-investigator
