Fig. 1From: Potential of whole-body dual-energy X-ray absorptiometry to predict muscle size of psoas major, gluteus maximus and back musclesDual-energy X-ray absorptiometry (DXA) scan with lean mass analysisColors in the DXA images represent tissue densities, with yellow (fat) being the lowest density and blue (bone) being the highest density. Trunk muscle mass is defined as the trunk fat-free mass, excluding the head and all limbsBack to article page
