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.

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 ...

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.

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-

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 ...

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 ...

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.

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.

Bone Mineral Content in Infants-Reply

Archives of Pediatrics & Adolescent Medicine, 1987
In Reply .—We do not believe that BMC and total body calcium are comparable, nor are they intended to be. Bone mineral content in adults is highly correlated to total body calcium in cross-sectional studies in which there is no longitudinal bone growth component to total body calcium.

Bone mineral content in patients with calcium urolithiasis

Metabolism, 1979
125I-photon absorptiometry was used to determine bone density (bone mineral content/bone width) in the distal third of the radius in 117 patients with absorptive hypercalciuria, 44 with renal hypercalciuria, 53 with primary hyperparathyroidism, and 69 patients with osteoporosis.
