Assessment of Bone Mineral Content in the Internal Bone Volume

Acta Radiologica, 1991
A 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.

Diet, Exercise, and Bone Mineral Content

Annals of Internal Medicine, 1985
Excerpt To the editor: The study of trabecular and cortical bone loss in healthy men by Drs. Meier, Orwoll, and Jones (1) had a flaw in the experimental design.

Relations of Bone Mineral Content, Ash Weight and Bone Mass

Clinical Orthopaedics and Related Research, 1980
Bone 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 ...

Assessment of Bone Mineral Content in Children

Journal of Pediatric Orthopaedics, 1991
Quantitative 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.

Scuba diving does not affect bone mineral density or bone mineral content

Joint Bone Spine, 2011
Scuba diving is a very specialized, physically demanding activity. The bones of divers are subjected to stress from water pressure, from the forces generated when their muscles resist water pressure, and from weightlessness. Notably, few studies have addressed the effects of diving on bone mineral density (BMD) and bone mineral content (BMC), and the ...

Familial aggregation of bone mineral density and bone mineral content in a Chinese population

Osteoporosis International, 2005
Familial aggregation of bone mineral density (BMD) and bone mineral content (BMC) has been shown in twin and familial studies, but most sample sizes were small. We here report a large familial aggregation study in a Chinese population. A total of 13,973 siblings aged 25-64 years from 3,882 families were enrolled from Anhui, China. We assessed the whole-

Bone mineral density and bone mineral content among female elite athletes

Bone, 2019
Exercise is a protective factor for the appearance of osteoporosis, but not all physical activities have the same effect on bones. Low-impact sports, like swimming, may a have a negative or no effect. The aim of the present study is to evaluate bone mineral density (BMD, g/cm2) and bone mineral content (BMC, kg) among female high performance athletes ...

Effect of prepubertal ovariohysterectomy on bone mineral density and bone mineral content in puppies

Acta Veterinaria Hungarica, 2005
In this study, dual energy X-ray absorptiometry (DXA) was performed on the calcaneus (CAL) and accessory carpal bone (ACB) of early-age neutered (n = 11) and sham-operated puppies (n = 10) to investigate changes in bone mineral density (BMD) and bone mineral content (BMC) over time.

Signalment differences in bone mineral content and bone mineral density in canine appendicular bones

Veterinary and Comparative Orthopaedics and Traumatology, 2008
SummaryThe objective was to determine signalment-related differences in bone mineral content (BMC) and bone mineral density (BMD) in dogs. Unilateral appendicular bones were harvested from 62 canine cadavers. Middiaphyseal regions of interest (ROIs) were scanned using a Hologic® DXA device Braincon, Vienna, Austria).

Roentgenographic Estimation of the Mineral Content of Bone

Radiology, 1950
It 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.
