Fully automated CT-based body composition analysis in a 93-year-old female with history of both colon and breast cancer.Post-contrast CT image at the L1 vertebral level demonstrates automated segmentation and display of skeletal muscle (red), visceral fat (amber), subcutaneous fat (blue), aortic calcium (bright yellow), liver (brown), spleen (orange), and trabecular bone (green). These all represent examples of “explainable artificial intelligence” that can be visually confirmed and compared against analogous manual measures, if desired.
