Fig. 2From: CT-based analysis of muscle volume and degeneration of gluteus medius in patients with unilateral hip osteoarthritisMuscle volume and fatty degeneration of the gluteus medius (GM). By tracing the cross-sectional areas of the GM on every third slice of the CT images using three-dimensional (3D) image analysis software (stripe area), GM muscle was reconstructed three-dimensionally (colored area). Muscle volume and fatty degeneration of the reconstructed GM were quantified using dedicated softwareBack to article page
