Main purpose of this study is to examine the effect of aging on the mineral density and morphology of human bones. The mineral density and morphology of radius and tibia from groups of young and old persons were measured by using an X-ray CT scanner and analyzed by the pQCT (peripheral Quantitative Computed Tomography) method. The results showed a decrease in volumetric bone density of all parts of both raclii and tibiae in the group of old persons. It was found that the rate of decrease depends on the location of the bones. The morphology change indicates that both the cortex area and the cortex thickness of the proximal radius for old persons were slightly smaller than those for young persons.
