Study Summary
Constrictive bronchiolitis is an uncommon lung disease that has been described in Veterans of conflicts in Iraq and Afghanistan. Although these Veterans have evidence of constrictive bronchiolitis on lung biopsies, non-invasive tests such as pulmonary function tests (PFTs) are often normal. This study will determine whether analysis of fluoroscopy images using the 4Dx XV Ventilation Analysis software developed by 4D Medical will be able to detect constrictive bronchiolitis in Veterans better than PFTs.
