Dual-photon absorptiometry of the proximal tibia
Archives of Orthopaedic and Traumatic Surgery, 1987Dual-photon absorptiometric bone-mineral assay, penetration tests, and axial compression tests of the proximal tibial epiphyses were carried out in 18 human cadaver knees. The reproducibility of bone mineral assay was within +/- 12% (95% tolerance limits).

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.

Single X-ray absorptiometry: Performance characteristics and comparison with single photon absorptiometry [PDF]
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).

The reproducibility of single photon absorptiometry in a clinical setting
European Journal of Nuclear Medicine, 1989The reproducibility of single photon absorptiometry (SPA) results for detection of changes in bone mineral content (BMC) was evaluated in a clinical setting. During a period of 18 months with 4 different sources, the calibration scans of an aluminium standard had a variation of less than 1% unless the activity of the 125I source was low.

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%.

Single-Photon Absorptiometry [PDF]
, 1988 Single-photon absorptiometry (SPA) was first described by Cameron and Sorenson (1963) in an effort to overcome the problems inherent in the use of film densitometry. The basic configuration for the single-photon systems commercially available today was introduced in 1972 (Mazess and Cameron, 1972).

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 [PDF]
, 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).

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.
