Dual photon absorptiometry of the proximal tibia
Calcified Tissue International, 1989Bone mineral content (BMC) and bone mineral density (BMD) of the proximal tibia were determined by dual photon absorptiometry on 44 women, aged 23-87 years. The area of the tibia measured was a 2.01 cm region immediately distal to the medial and lateral tuberosities.

Dual-energy X-ray absorptiometry versus single photon absorptiometry of the radius
Calcified Tissue International, 1991Radial diaphyseal bone mineral density (BMD) was measured at the standard one-third site by dual-energy X-ray absorptiometry (DEXA) and by 125I single photon absorptiometry (SPA) in 70 consecutive subjects, aged 12-86 years, with metabolic disorders of the skeleton. Each patient was measured once by the DEXA (Hologic QDR-1000) instrument and four times

Osteoporosis International, 1995
The aim of the present study was to evaluate a new device for measurement of forearm bone mass using the technique of single X-ray absorptiometry (SXA, DTX-100; Osteometer A/S, Rødovre, Denmark), and to compare the performance with the more traditional single photon absorptiometry (SPA, DT 100; Osteometer A/S, Rødovre, Denmark).

Rinsho hoshasen. Clinical radiography, 1990
BMC and BMD of the total body bone and lumbar spine were measured in normal control and patients with metabolic bone diseases by DPA (Dichromatic Bone Densitometer Model 2600, Norland corporation). Also, total body fat mass was measured in patients with obesity.

Sensitivity of dual-photon absorptiometry in spinal osteoporosis
Calcified Tissue International, 1988Lumbar spine bone mass and density were measured with Dual photon absorptiometry (DPA) in 60 patients with crush fractures and 60 age-matched normal women. Short-term reproducibility of bone mineral density (BMD) was 1.3% in normal women and 2.5% in osteoporotic women; long-term reproducibility in normal women was 2.2%.

Value of Single Photon Absorptiometry in Osteoporosis Screening
Clinical Nuclear Medicine, 1988Radial bone mineral content and bone mineral density were measured in 1515 women referred for osteoporosis screening. A detailed questionnaire allowed the selection of 1069 normal white women for further analysis who had no historical evidence of bone disease or predisposing factors for bone disease. The nondominant radius was measured at two locations:

A Renal Transplant Seen on Dual Photon Absorptiometry
Clinical Nuclear Medicine, 1993A 25-year-old man who had a chronic rejection of renal transplantation performed 4 years earlier develops seccondary hyperparathyroidism. Dual-photon absorptiometry of the lumbar spine and right femur were performed to evaluate changes in bone mass. A roundish highdensity area was seen in the right iliac region.

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).

Dual Photon Absorptiometry The Importance of Clinical Correlation
Clinical Nuclear Medicine, 1988Dual photon absorptiometry is a reliable method of assessing bone mineral density. However, distortions of bony architecture, which may not be evident from the low-resolution images provided, can complicate the evaluation and lead to misleading findings. A case is presented which describes the importance of clinical and radiographic correlation.

Photon absorptiometry of bone after successful renal transplantation
The British Journal of Radiology, 1977Photon 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.
