Inspiratory and expiratory CT analyses of the diaphragmatic crus in chronic obstructive pulmonary disease

Abstract: Purpose This study aimed to investigate the association between the results of pulmonary function tests (PFTs) in patients with chronic obstructive pulmonary disease (COPD) and the size of their diaphragmatic crus (DC) using inspiratory and expiratory CT. Materials and methods Thirty-three patients who underwent inspiratory and expiratory CT and PFTs between July and December 2019 were studied retrospectively. The short axis, long axis, and cross-sectional… Show more

“…56 The fiber is shortened by about 28% compared to healthy subjects, with an increase in collagenous tissue. 3,57 The regeneration capacity of the fibers is reduced (increased myostatin values), as is the ability of the satellite cells to repair the various muscle components. 3,44 FEV1 is inversely related to diaphragm hypotrophy.…”
