Comp2Comp: Rapid, Automated Body Composition Analysis

Comp2Comp is an open-source Python package for rapid and automated body composition analysis of CT scans. This package offers models, post-processing heuristics, body composition metrics, automated batching, and polychromatic visualizations. Comp2Comp currently computes body composition measures for bone, skeletal muscle, liver, vasculature, visceral and subcutaneous adipose tissue on CT scans of the abdomen. Such imaging-based biomarkers allow for assessing musculoskeletal as well as cardiometabolic disorders. Given that abdominal CT scans are routinely performed in the clinic, the use of Comp2Comp enables conducting population-level studies.
