endobronchial optical coherence tomography images from the
3rd to 9th generation of bronchi
Compared with control subjects, patients with asthma were characterized
by significant airway wall thickening and luminal narrowing. More
prominent structural abnormalities were associated with greater severity
of asthma, as evidenced by the decreased airway caliber and greater
airway wall area.
