Evaluation of Methods of Bone Mass Measurement

摘要: Quantitative assessment of bone mineral is necessary for an understanding those factors which influence the development osteoporosis and investigation possible remedial measures. Most studies have been upon groups, rather than individuals, substantial overlap between osteoporotic normal subjects different disease treatment groups has shown, in spite significant differences mean values. However, it now being argued that there a case screening individuals to identity with mass low enough suggest high risk vertebral or femoral fracture, so prophylactic measures may be recommended. Accuracy clearly important all measurements, especially when comparisons centres are used; longitudinal precision paramount. Techniques must also carry negligible risk, from radiation example. The most appropriate part skeleton particular purpose investigated. These will considered here.
