[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:

[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 ...

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.

Dual photon absorptiometry using a gamma camera.
Australasian physical & engineering sciences in medicine, 1990The most common technique for bone mineral densitometry is Dual Photon Absorptiometry with a dedicated scanning device. In principle, a gamma camera could be adapted to perform the same function, but little work along these lines has been reported in the literature.

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.

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 ...
