Comparative StudyTotal body and regional bone mineral densitometry (BMD) and soft tissue measurements: correlations of BMD parameter to lumbar spine and hip.
Bone loss in men and women seems to differ according to the skeletal regions or particular areas being evaluated. Dual energy X-ray absorptiometry (DXA) is the method of choice for measuring total body and regional bone mineral area density (BMD). The aim of the study was to evaluate the importance of DXA measurements of total body in relation to lumbar spine and hip in different scan beam designs. ⋯ There were also highly significant correlations between the lumbar spine (or hip) and total body, being best for the subregional thorax. Our data demonstrate short-and mid-term precision errors of BMD with reproducible results for most areas in SB and FB design, whereas soft tissue measurements vary depending on the area being measured. Furthermore, there is a close relationship between BMD values of total body total and subregional parameters and lumbar spine and hip scans, respectively.
