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%.

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.

The Use of Photon Absorptiometry in the Diagnosis of Renal Osteodystrophy
Radiology, 1973By using a 125I collimated point source to measure bone mineral, 700 measurements were obtained from the cortical bone of the lower arm in 303 patients with renal failure representing every stage of the disease. Of these patients, 123 had received transplants.

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.

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.

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.

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).

An evaluation of dual-energy X-ray absorptiometry and comparison with dual-photon absorptiometry
Osteoporosis International, 1992Dual-photon absorptiometry (DPA) is a well-established procedure for measuring bone mineral density (BMD). Recently, dual-energy X-ray absorptiometry (DXA) has become available, which has the ability to measure BMD both regionally and in the total body (TB). We have evaluated the in vivo and in vitro precision of a DXA instrument and compared it with a

1988
The potential of dual-photon absorptiometry (DPA) for noninvasive bone measurements was originally reported by Reed (1960) and by Cameron and Sorenson (1963). The first equipment utilizing this technique was constructed by Reed and Atkinson (1965; Reed, 1966), and methods for measurement of the BMC of the lumbar vertebrae in vivo were subsequently ...
