Dual-energy X-ray absorptiometry (DXA, or DEXA [1]) is a means of measuring bone mineral density (BMD) with spectral imaging. Two X-ray beams, with different energy levels, are aimed at the patient's bones. When soft tissue absorption is subtracted, the bone mineral density (BMD) can be determined from the absorption of each beam by bone. Dual ...
The trabecular bone score is a textural parameter that can be applied to DEXA, which quantifies the local variations in gray level. TBS is derived from the evaluation of the experimental variogram, obtained from the grayscale DEXA. [citation needed] It was found that TBS is a reflection of the structural condition of the bone microarchitecture.
A scanner used to measure bone density using dual energy X-ray absorptiometry. Bone density, or bone mineral density, is the amount of bone mineral in bone tissue.The concept is of mass of mineral per volume of bone (relating to density in the physics sense), although clinically it is measured by proxy according to optical density per square centimetre of bone surface upon imaging.

Since Lady Gaga's "Bad Romance" in 2009, every video that has reached the top of the "most-viewed YouTube videos" list has been a music video. In November 2005, a Nike advertisement featuring Brazilian football player Ronaldinho became the first video to reach 1,000,000 views. [1] The billion-view mark was first passed by Gangnam Style in ...
A wide variety of body composition measurement methods exist. The gold standard measurement technique for the 4-compartment model consists of a weight measurement, body density measurement using hydrostatic weighing or air displacement plethysmography, total body water calculation using isotope dilution analysis, and mineral content measurement by dual-energy X-ray absorptiometry (DEXA).

About 22 million women and 5.5 million men in the European Union had osteoporosis in 2010. [15] In the United States in 2010, about 8 million women and between 1 and 2 million men had osteoporosis. [13] [16] White and Asian people are at greater risk. [3] The word "osteoporosis" is from the Greek terms for "porous bones". [17]

The International Osteoporosis Foundation and the European Calcified Tissue Society recommend pharmacological therapy for osteoporosis in postmenopausal women and men ≥70 years, with a previous fragility fracture, or a dose equivalent of prednisone ≥7.5 mg daily for ≥3 months. For premenopausal women and men <50 years taking steroids for ...
