    Innovative tool gives researchers new look at the nasal airway in CF patients

    A paper published today in Science Translational Medicine describes a simple, minimally invasive new tool for viewing differences in the nasal airways of cystic fibrosis patients in vivo at a cellular level. The new technique provides high-resolution images of the hair-like structures called cilia that line nasal airways as well as of the detailed features of the clearance of mucus, which is impaired in people with CF, causing significant morbidity. The imaging catheter, which is about 2 mm in diameter, uses optical coherence tomography with a resolution of about 1 micrometer — a 50th the size of a human hair — allowing ...

    1. We’ve done a lot of benchtop imaging with micro-OCT, but this is the first time we’ve been able to use it in people...It’s unprecedented to see this pathophysiology dynamically in living patients. It will allow us to begin to understand things we never even knew were there.
