Measurement of spine and total body mineral by dual-photon absorptiometry

摘要: The use of Gd-153 dual-photon absorptiometry at 43 and 100 keV to measure individual-bone total-body bone minerals is discussed in a survey recent studies on humans, phantoms, monkeys. Precision errors as low 1 percent have been achieved vivo, suggesting the sequential measurements immobilization space-flight effects.
