Prognostic value of early changes in artificial intelligence-based computed tomography-measured body composition in pediatric osteosarcoma receiving neoadjuvant chemotherapy

Figure 2 Representative case of a 12-year-old male with osteosarcoma of the distal femur who received neoadjuvant chemotherapy. A: Pre-chemotherapy axial computed tomography at L3 with automated segmentation (skeletal muscle = red, visceral fat = yellow, subcutaneous fat = blue); B: Post-chemotherapy axial computed tomography at L3 with automated segmentation. Tissue area and density values are shown for pre- and post-chemotherapy scans with the Δ values. Tissue area and density were automatically calculated using Visage version 7.1. SMI: Skeletal muscle index; VATI: Visceral adipose tissue index; SATI: Subcutaneous adipose tissue index; SMD: Skeletal muscle density; HU: Hounsfield unit.
