A scanning principle utilizing a dual beam of penetrating radiation and a new instrument designed to measure the fat to fat-free ratio of the soft tissue of the upper arm by differential absorptiometry were tested in 24 volunteers for short and long-term precision. Reproducibility of the adiposity measurements was generally good, and positive correlations were obtained with other variables such as weight and skinfold. Regional adiposity measurement by absorptiometry shows promise for clinical application.
