Regional bone mineral measurements.
Total body dual-photon transmission scanning was performed in 9 control persons, 15 athletes and in 5 patients with eating disorders. Total body bone mineral mass was measured, with a reproducibility of 2%; for regional bone mineral mass the reproducibility was 4%. The fraction of total bone mineral in the spines and heads of women is greater than in men. Patients with eating disorders have a smaller fraction of total body mineral in the pelvis than female controls. Weight lifters have a significantly greater mineral mass in the trunk region than other athletes and male controls. These and other differences are consistent with the conclusion that total body dual-photon absorptiometry allows quantitation of the distribution of mineral within the skeleton.
