OSTEOPOROSIS IN HYPERTHYROIDISM ESTIMATED BY PHOTON ABSORPTIOMETRY
Acta Endocrinologica, 1979ABSTRACT The degree of osteoporosis in hyperthyroidism before and during treatment with carbimazole was studied by photon absorption technique of the right forearm and calcaneus. In addition serum total calcium, serum ionized calcium, serum phosphorus and serum alkaline phosphatase were determined.

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.

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.

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:

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.

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

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.

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
