Introduction,sceptible to fracture. In the nineteenth century, several physicians noted the unusual frequency of fractures in the elderly population, but they were not aware of the disease process, osteoporosis, as the underlying cause (Davies and Saha, 1985). Senile osteoporosis was first described in 1926 by A

Radiographic Film Methods, that there was a means of visualizing the disease. As the life expectancy in humans increased in the early decades of the twentienth century, more people were living long enough to manifest the disease. In the 1930s and 1940s, routine x-ray film methods were used to detect osteoporosis (Davies and

Scattering Methods in Densitometry,graphic films for the detection of x-rays. Single-photon absorptiometry requires the use of scintillation detectors for determining the gamma-ray transmission through bone and soft tissue, as does the dual-photon method. CT densitometry is based upon the detection of the transmitted x-rays or gamma

Activation Analysis Methods,otal-body calcium. However, only a few laboratories are able to perform these procedures because of the requirements for the appropriate particle sources and the need to detect extremely low levels of activated elements within the human body. Total-body activation analysis systems are expensive and

Dual-Photon Absorptiometry,oting that forearm BMC measurements are not very useful in predicting BMC in the axial skeleton (Dalen and Jacobsen, 1974; Madsen, 1977) especially in diseased states (Krolner et al., 1980; Krolner et al., 1982c). Dunn et al. (1980) developed the dual-photon method for measuring the bone mineral content in the hip.

Book 1988ever before in the diagnosis and treatment of degenerative diseases of bone such as osteoporosis. The public perception of osteoporosis and its prevention has been recently heightened. Because osteoporosis is widespread, especially in women, and leads to an increase in fractures in our population, m
