Body Composition by Dual-Photon Absorptiometry and Dual-Energy X-Ray Absorptiometry
1990Dual-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).

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 ...

Photon absorptiometry, bone densitometry and the challenge of osteoporosis
Physics in Medicine and Biology, 2006During the lifetime of Physics in Medicine and Biology, osteoporosis has been recognized as the cause of a major health burden for societies, particularly within developed countries. The health detriment is associated with the consequences of bone fractures and the subsequent increases in morbidity and mortality.

[Applications and results of photon absorptiometry].
Minerva endocrinologica, 1992Bone 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:

Monitoring fluoride therapy in osteoporosis by dual photon absorptiometry
Bone, 1987Dual 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.

Total body composition by dual-photon (153Gd) absorptiometry
The American Journal of Clinical Nutrition, 1984The lean-fat composition (%FATR) of soft tissue and the mineral mass of the skeleton were determined in vivo using dual-photon (153Gd) absorptiometry (dose under 2 mrem). A rectilinear raster scan was made over the entire body in 18 subjects (14 female, 4 male). Single-photon absorptiometry (125I) measured bone mineral content on the radius. Percentage

Precision of dual photon absorptiometry measurements.
Journal of nuclear medicine : official publication, Society of Nuclear Medicine, 1986One of the important uses of bone absorptiometry is to examine the rate of bone mineral change in order to evaluate therapy and to identify individuals who need therapy. Generally, this involves comparing the difference between two scans obtained months to years apart.

Vertebral and Peripheral Bone Mineral Content by Photon Absorptiometry
Investigative Radiology, 1977Dual 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 ...

[Double photon absorptiometry in renal osteodystrophy].
Wiener klinische Wochenschrift, 1990Bone mineral content (BMC) of the lumbar spine (L2-L4), femoral neck, Ward's triangle and the trochanteric region was measured in 52 consecutive patients on maintenance haemodialysis. In the whole group the median BMC value as percentage of sex- and age-matched normal means was significantly decreased only in Ward's triangle (91.7%; p less than 0.02 ...

Measurements of Bone Mineral by Photon Absorptiometry
1987The 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 ...
