Objective: To investigate a fully automated abdominal CT-based muscle tool in a large adult screening population.Methods: A fully automated validated muscle segmentation algorithm was applied to 9310 non-contrast CT scans, including a primary screening cohort of 8037 consecutive asymptomatic adults (mean age, 57.1 +/- 7.8 years; 3555M/4482F). Sequential follow-up scans were available in a subset of 1171 individuals (mean interval, 5.1 years), Muscle tissue cross-sectional area and attenuation (Hounsfield unit, HU) at the L3 level were assessed, including change over time.Results: Mean values were significantly higher in males for both muscle area (190.6 +/- 33.6 vs 133.3 +/- 24.1 cm(2), p
