Fig. 2From: Computed tomography-derived area and density of pectoralis muscle associated disease severity and longitudinal changes in chronic obstructive pulmonary disease: a case control studyComputed tomography (CT) scans were used to assess the pectoralis muscle area and density. a, the CT axial slice above the aortic arch level shows the pectoralis muscle segmentation (red, pectoralis major muscle; blue, pectoralis minor muscle). b and c, differences between pectoralis muscle densities are depicted in CT imagesBack to article page
