Abstract
Objective To assess the significance of quantitative ultrasound (QUS) in diagnosis of osteoporosis.and the effectiveness of dual energy X-ray absorptiomentry(DEXA) in evaluation of bone structure. Methods Calcaneus BUA and SOS were measured by QUS in 40 healthy adults.Bone mineral density(BMD)of whole body,lumbar,lateral spines and hip were simultaneously determined by DEXA. Results Both calcaneus BUA and SOS were highly correlated with BMD in most of regions( r =0 35～0 62, P 0 05 or 0 01).There was a good linear relationship between BUA and BMD of hip,and also between SOS and BMD of lumbar spines. Conclusion QUS is a better method for diagnosis of osteoporosis and evalution of bone intensity.BMD of hip and lumbar spines have significant value in evaluation of bone structure.
