Osteoporosis is defined as a decrease in bone mass and structural changes in bone leading to an increased fracture incidence. Therefore, early diagnosis in terms of prophylaxis and treatment are of great interest. Over the past several decades there has been considerable progress in the development and application of non-invasive methods of bone mass measurements or bone densitometry. This article reviews basic methodology and developments in bone densitometry including the early approaches like radiogrammetry, photo densitometry, neutron activation analysis and compton scattering techniques, present methods like single and dual x-ray absorptiometry and quantitative computed tomography, and recent developments like quantitative ultrasound, magnetic resonance techniques and structural analysis. The widespread interest in bone densitometry will initiate further improvement of established methods and development of new applications. [ABSTRACT FROM AUTHOR] |
