Dual-energy X-ray Absorptiometry
Journal of Clinical Densitometry, 2017Bone mineral density (BMD) measurement by dual-energy X-ray absorptiometry (DXA) is the most commonly used method to assess fracture risk. DXA utilizes two different energy X-rays to calculate BMD and, by comparison to a young normative database, the T-score.

Single- and Dual-Energy: X-Ray Absorptiometry
European Radiology, 1997Osteoporosis is the most common of the metabolic disorders of bone. The condition is characterised by reduced bone mass and easy (fragility) fracture. Such fractures can occur in any site but are most frequent in the wrist, spine (vertebral body) and hip — areas of the skeleton rich in trabecular bone. Such fractures, and particularly those in the hip,

Dual-energy X-ray absorptiometry: A review
Journal of Renal Nutrition, 1999Dual-energy X-ray absorptiometry (DXA) has been recently used for body composition analysis in dialysis patients. It is based on the principle that X-rays passed through various body tissues have different attenuation and, therefore, can be differentiated.

Dual-Energy X-ray Absorptiometry in Osteopetrosis
Southern Medical Journal, 2000We have used dual-energy x-ray absorptiometry (DXA) in evaluation and follow-up of a patient with osteopetrosis, before and after cord blood transplantation. Other methods of follow-up in such cases have been described, but the use of DXA has not previously been reported.

Dual-Energy X-Ray Absorptiometry
2007Early attempts at bone densitometry used conventional x-rays with a step wedge made from an aluminum or ivory phantom included in the field of view as a means of calibration. The bone density was calculated by a visual comparison of the density of the bone and the known densities of the each of the steps on the phantom.

[Dual energy X-ray absorptiometry].
Nihon rinsho. Japanese journal of clinical medicine, 1994Dual energy X-ray absorptiometry (DXA) has been widely used in Japan. In this article, we described our lateral measurement of lumbar vertebral body, and reviewed the fracture threshold and the diagnosis of osteoporosis. The bone mineral density was measured in the anteroposterior projection (L2-4BMD) and in the lateral projection (L3 latBMD) by XR-26.

Dual-Energy X-Ray Absorptiometry in Early Life
Hormone Research, 1997Dual-energy X-ray absorptiometry (DXA) is a safe and quick technique, and requires little cooperation from the patient. DXA has therefore been introduced progressively in paediatrics and neonatology to study bone mineral content and body composition.

An Update on Dual-Energy X-Ray Absorptiometry
Seminars in Nuclear Medicine, 2010Dual-energy x-ray absorptiometry (DXA) scans to measure bone mineral density at the spine and hip have an important role in the evaluation of individuals at risk of osteoporosis, and in helping clinicians advise patients about the appropriate use of antifracture treatment.

Dual-Energy X-Ray Absorptiometry
2003Osteoporosis is the most common metabolic bone disease. It is characterised by reduced bone mass, altered bone architecture and the clinical consequence of easy fracture with little or no trauma (low-trauma fractures). These fractures tend to occur most commonly in sites of the skeleton that are rich in trabecular bone: the wrist, spine and hip.
