    Sep 17, 2002 No studies have evaluated the optimal intervals for repeated screening. Because of limitations in the precision of testing, a minimum of 2 years may be needed to reliably measure a change in bone mineral density; however, longer intervals may be adequate for repeated screening to identify new cases of osteoporosis

    Quantitative ultrasound methods to assess bone mineral

    Measurement of bone mineral status may be a useful tool in identifying the children who could be exposed to an increased risk of osteoporosis in adulthood. Dual energy x-ray absorptiometry and peripheral quantitative computed tomography may be used to this purpose, but the exposure to ionizing radiation is a limiting factor for preventive

    Jun 26, 2018 While several bone measurement tests similarly predict risk of fractures, DXA provides measurement of bone mineral density (BMD), and most treatment guidelines use central DXA to define osteoporosis and the treatment threshold to prevent osteoporotic fractures. Other screening tests include peripheral DXA and quantitative ultrasound (QUS
