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 ...

Precision of dual photon absorptiometry measurements.

Journal of nuclear medicine : official publication, Society of Nuclear Medicine, 1986
One 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.

[Double photon absorptiometry in renal osteodystrophy].

Wiener klinische Wochenschrift, 1990
Bone 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 ...
