Assessment of Bone Mineral Content in Children
Journal of Pediatric Orthopaedics, 1991Quantitative digital radiography (QDR) is a new technique for measuring bone mineral content that offers improved precision, shorter study times, and less radiation exposure than single-photon absorptiometry (SPA), dual-photon absorptiometry (DPA), and quantitative computed tomography (CT) scanning.

Bone Mineral Content and Fragility Fractures
Clinical Orthopaedics and Related Research, 1977In 249 patients with fractures characteristic of bone fragility, i.e. femoral neck fracture, vertebral crush fracture, fracture of the upper end of the humerus, Colles' fracture, fracture of the lateral condyle of the tibia and various ankle fractures, and forearm bone mineral content was measured by gamma absorptiometry.

Assessment of Bone Mineral Content in the Internal Bone Volume
Acta Radiologica, 1991A method for assessing values related to bone density and mass is described. Mean attenuation and pixel area are measured in pixels selected on the basis of CT units. The method is to a large extent computerized and not dependent on manual positioning or outlining of a region of interest.

Bone mineral content and mechanical strength of the femoral neck.
Acta Orthopaedica Scandinavica, 1976The bone mineral content of the femoral neck of 61 autopsy specimens was assayed by x-ray spectrophotometry. The mechanical strength of the specimens was also determined experimentally by applying a compressive force perpendicularly to the shaft.

Roentgenographic Estimation of the Mineral Content of Bone
Radiology, 1950It is well known that adult bone is not merely an inert structural material but is a living tissue with a mineral content which fluctuates under the influence of endocrine and enzyme activity. Hevesy (1) showed, by the use of radiophosphorus, that there is active metabolism in bone.

A comparative study of the usefulness of the femoral trabecular-pattern index (Singh index) and bone mineral content measurement by photon absorption in senile osteoporosis was performed in 106 white women, seventy to ninety-five years old. In 17% of the

Relations of Bone Mineral Content, Ash Weight and Bone Mass
Clinical Orthopaedics and Related Research, 1980Bone mineral content (BMC) was measured by photon absorptiometry in fresh bone specimens: 35 iliac crest and 39 forearms were used. BMC was related to ash weight, fat-free weight and the amount of bone determined by quantitative histologic methods. Ninety-five per cent of the variation in bone mineral concentration (BMC') in the iliac crest could be ...

Estimation of total body calcium from the bone mineral content of the forearm.
Scandinavian Journal of Clinical and Laboratory Investigation, 1975The representativity of forearm in bone mineral content (BMC) measurements for estimation of total body calcium is investigated in this article. It is shown that there is a very high correlation between weight and calcium content of examined bone pieces,

Determination of bone mineral content using CT scanning.
AJR. American journal of roentgenology, 1976The usefulness and accuracy of CT scanning in the determination of bone mineral content is studied. The radius in 31 patients of both sexes and varying ages was examined using both the Norland-Cameron bone mineral analyzer and the CT scanner.

The bone mineral content (BMC) in the lumbar spine, femoral neck, and femoral shaft in 46 women ranging in age from 60 to 89 years with fractures of the femoral neck was measured by dual photon absorptiometry and compared with that of 38 healthy women in
