Ultrasound and dual X-ray absorptiometry measurement of the calcaneus: influence of region of interest location.

abstract：:Normal rat bone maturation has been studied using biochemical methods and hydrazine separation of matrix and mineral for X-ray diffraction. In the bone, the amount of mineral increases between 4 and 22 weeks of age, while in the matrix, the ratio of noncollagenous protein to collagen progressively decreases. In minera...
