 (əb-zôrp′tē-ŏm′ĭ-trē, -sôrp′-)
A method of chemical analysis in which a sample of a substance is exposed to electromagnetic radiation, and the amount of radiation absorbed is measured to determine the chemical composition or concentration of the substance.

Contract Awarded for 1 sets of whole-body double energy x-ray absorptiometry
Patients and methods: In this study, we reanalyzed 323 dual energy X-ray absorptiometry (DXA) reports, by evaluating the scan images for proper patient positioning and scan analysis.
For the study, researchers measured bone density using three-dimensional computed tomography (CT) called quantitative CT and dual-energy x-ray absorptiometry, also called DXA.
There are certain techniques for accurately assessing total body fat such as underwater weighing (UWW),7,8 dual energy X-ray absorptiometry (DEXA), and isotope dilution, but they are extremely expensive and are only possible in specialized research centers.
Bone mineral density z-score was measured at lumbar spine with Dual Energy X-Ray Absorptiometry at L1-L4 lumbar vertebra.
Researchers used dual x-ray absorptiometry scans to assess bone mineral density (BMD) at the lumbar spine, femoral neck, and hips of the study participants and assigned the women a Trabecular Bone Score, which indicates the quality of bone structure, based on their BMDs.
These methods include: hydrodensitometry (HW), dual-energy x-ray absorptiometry (DXA), isotope dilution (ID), skinfold thickness (SKF) body mass index (BMI), near-infrared interactance (NIR) and bioelectrical impedance analysis (BIA) (9,10,22).
The global bone densitometers market segmentation is based on technology (axial bone densitometry, dual energy x-ray absorptiometry, quantitative computed tomography, peripheral bone densitometry, single energy x-ray absorptiometry, dual energy x-ray absorptiometry, radiographic absorptiometry, quantitative ultrasound, peripheral quantitative computed tomography), and end users (hospital-based bone densitometers, clinic-based bone densitometers).
The new study extends the findings from the earlier research using dual X-ray absorptiometry, a more rigorous method of measuring body composition.
Quality is ensured for meat processed on the production line by the use of the company's third generation Dual Energy X-ray Absorptiometry (DEXA) technology that discriminates between fat and lean portions of 100 percent of the throughput products.
Total-body dual energy X-ray absorptiometry (DXA) scanning assessed muscle mass and handgrip strength and a chair-rising test evaluated strength at the beginning and end of the study.
An alternative method to be set as a gold standard method is Dualenergy X-ray absorptiometry (DEXA).
