Single- and dual-photon absorptiometry in osteoporosis and osteomalacia

Seminars in Nuclear Medicine, 1987
Single- and dual-photon absorptiometric methods have been used in the past to identify populations at risk for bone loss, to define the osteoporotic syndrome in terms of bone mass, and to evaluate treatment regimens to prevent bone loss. Technical improvements have made these procedures available for the nontraumatic measurement of bone mineral in the ...

Body composition by photon absorptiometry.

Canadian journal of sport sciences = Journal canadien des sciences du sport, 1990
Whole-body dual photon measurements of body composition were made in 9 controls, 15 athletes and 5 patients with eating disorders. Measurements of lean body mass, mineral mass and fat mass were accurate. Lean body mass and fat mass were measured with reliabilities of about 0.8 kg while for total body bone mineral mass, the reliability was about 60 g ...

Photon absorptiometry.

American journal of physiologic imaging, 1988
Recently, there has been a renewed interest in the detection and treatment of osteoporosis. This paper is a review of the merits and limitations of the various noninvasive modalities currently available for the measurement of bone mineral density with special emphasis placed upon the nuclear medicine techniques of single-photon and dual-photon ...

[Applications and results of photon absorptiometry].

Minerva endocrinologica, 1992
Bone mineral content (CMO, mg/cm2) was measured at the distal radius by dual photon absorptiometry (DPA, I125, Am241) in 1.161 women (w), aged 20-87 years. Women were subdivided into different groups according to the presence and duration of menopause. For gross evaluation of spinal osteoporosis (OP), the results of spinal X-rays were graded as follows:

Body Composition by Dual-Photon Absorptiometry and Dual-Energy X-Ray Absorptiometry

1990
Dual-energy projection methods have been used over the past decade for non-invasive measurement of bone. Dual-photon absorptiometry (DPA) using a 153-Gd radionuclide source is used clinically in about 1000 centers to measure regional bone mineral density (BMD), particularly of the spine and proximal femur (Barden and Mazess, 1989).

Photon absorptiometry of bone after successful renal transplantation

The British Journal of Radiology, 1977
Photon absorptiometric measurements of the right lower femur were carried out at regular intervals of one to three months in 58 recipients of renal transplant. (1) During the first six months after transplant 57% showed a significant and abnormal rate of loss of bone mineral (mean 11.7% per year.

Monitoring fluoride therapy in osteoporosis by dual photon absorptiometry

Bone, 1987
Dual photon absorptiometry (DPA) was used to evaluate changes in bone mineral mass in 108 osteopenic patients. Ninety were treated with fluoride and 18 served as controls. All osteopenic patients and 9 of the controls took calcium and vitamin D supplements. In 16 women estrogens were combined with the fluoride therapy.

Estimation of Bone and Skeletal Weight by Direct Photon Absorptiometry

Investigative Radiology, 1971
The direct photon (125I) absorptiometric method for radiologic measurement of bone was used to examine the intercorrelations among determinations at various sites on the human ulna, radius, humerus and femur.

Measurements of Bone Mineral by Photon Absorptiometry

1987
The recognition of the socioeconomic impact of osteoporosis in our ageing population, with its associated morbidity and mortality from spinal, hip and radius fractures, has led to an increasing interest in bone mass and its measurement. As a result, several clinically tested methods are now available for diagnosing low bone mass, measuring the rate of ...

Vertebral and Peripheral Bone Mineral Content by Photon Absorptiometry

Investigative Radiology, 1977
Dual photon absorptiometry with 153Gd was used to determine the bone mineral content of the lumbar spine of 46 subjects. The bone mineral content of the radius and ulna were measured on these same subjects using single photon absorptiometry. The bone mineral content at the peripheral sites was not a very accurate indicator of absolute bone mineral ...
