Abstract
Bone mineral densitometry is a useful procedure for the early detection of metabolic bone diseases and bone density changes caused by long term drug use. Dual energy X-ray absorpt- iometry(DEXA), a recently developed diagnostic radiologic method for evaluating bone mineral density is widely used because of its high sensitivity, easily obtaine results. and low dose radi- ation exposure. The study was designed to obtain standard values of bone mineral density and its distribytion pattern with respect to age, sex, old, 30 males, 23 females by using Hologic QD R-2000 X-ray bone densitometer. We assessed the bone mineral density of the first to fourth l-umbar vertebral bones. The result obtained are as follows. 1) A positive correlation was noted between the age and bone mineral density with correlati-on coefficient(r) of 0.8105. More specifically, an increase in bone mineral density was noted wit h an increase in age. 2) The mean bone mineral density for male was 0.60¡¾0.09g/cm2 and 0.62¡¾0.11g/cm2 for f emale with no significant differences between both sexes. 3) A positive correlation was noted between bone mineral density and weight with a correlat-ion coefficient of 0.8227. 4) A positive correlation was also noted between bone mineral density and height with a cor-relation coefficient of 0.6951 5) Comparing the bone mineral density between Korean and American children shows no si-gnificant difference.
