Enhanced Muscle and Fat Segmentation for CT-Based Body Composition Analysis: A Comparative Study

arXiv:2401.05294v2 Announce Type: replace
Abstract: Purpose: Body composition measurements from routine abdominal CT can yield personalized risk assessments for asymptomatic and diseased patients. In particular, attenuation and volume measures of muscle and fat are associated with important clinical outcomes, such as cardiovascular events, fractures, and death. This study evaluates the reliability of an Internal tool for the segmentation of muscle and fat (subcutaneous and visceral) as compared to the well-established public TotalSegmentator tool.
Methods: We assessed the tools across 900 …
