The GE Revolution 256-row CT (General Electric Company, Boston, MA, USA, 2015) was used to scan the upper abdomen of the participants once each before and one week after the intervention. Participants were placed in a supine position with both arms raised. GSI scan parameters included a tube voltage 80, 140 kVp transient switching, tube current intelligent adjustment, layer thickness 5 mm, layer spacing 5 mm, and data were automatically imported into the GE ADW 4.7 workstation at the end of the scan. We selected the L3 level in the GE ADW 4.7 workstation and manually outlined the area of interest along the skeletal muscle using the X Section software within the workstation.
