ACURACY OF BONE MINERAL MEASUREMENT.

The use of nearly monochromatic radiation (l(125)) for the direct determination of bone mineral absorption in cadaver materials indicates that underlying bone components can be measured accurately on the flesh-covered forearm. The correlation of the bone mass, determined by this scanning technique, with actual bone weight is 0.96. The method is the most accurate yet demonstrated for bone with overlying tissue, and may prove suitable for these studies in vivo where it has not been possible to use previous roentgenologic techniques.

MEASUREMENT OF BONE MINERAL IN VIVO: AN IMPROVED METHOD.

The mineral content of bone can be determined by measuring the absorption by bone of a monochromatic, low-energy photon beam which originates in a radioactive source (iodine-125 at 27.3 kev or americium 241 at 59.6 kev). The intensity of the beam transmitted by the bone is measured by counting with a scintillation detector. Since the photon source and detector are well collimated, errors resulting from scattered radiation are reduced. From measurements of the intensity of the transmitted beam, made at intervals across the bone, the total mineral content of the bone can be determined. The results are accurate and reproducible to within about 3 percent.
