  2. Dual-energy X-ray absorptiometry - Wikipedia

    en.wikipedia.org/wiki/Dual-energy_X-ray...

    The radiation dose of current DEXA systems is small, [24] as low as 0.001 mSv, much less than a standard chest or dental x-ray. [25] [26] However, the dose delivered by older DEXA radiation sources (that used radioisotopes rather than x-ray generators) could be as high as 35 mGy, [27] [28] [29] considered a significant dose by radiological ...

  3. Bone density - Wikipedia

    en.wikipedia.org/wiki/Bone_density

    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.

  4. Trabecular bone score - Wikipedia

    en.wikipedia.org/wiki/Trabecular_bone_score

    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.

  5. Senile osteoporosis - Wikipedia

    en.wikipedia.org/wiki/Senile_osteoporosis

    Primary, or involuntary osteoporosis, can further be classified into Type I or Type II. [1] Type I refers to postmenopausal osteoporosis and is caused by the deficiency of estrogen. [1] While senile osteoporosis is categorized as an involuntary, Type II, and primary osteoporosis, which affects both men and women over the age of 70 years.

  6. Dual X-ray absorptiometry and laser - Wikipedia

    en.wikipedia.org/wiki/Dual_X-ray_absorptiometry...

    bone density studies for osteoporosis assessment Dual X-ray absorptiometry and laser technique (DXL) in the area of bone density studies for osteoporosis assessment is an improvement to the DXA Technique , adding an exact laser measurement of the thickness of the region scanned.

  7. Osteoporosis - Wikipedia

    en.wikipedia.org/wiki/Osteoporosis

    It affects women more than men due to the sharp fall in estrogen production that follows menopause. [193] Globally, it is estimated that 21.2% of women and 6.3% of men over the age of 50 have osteoporosis, corresponding to a total of around 500 million people worldwide. [194] About 15% of Caucasians in their 50s and 70% of those over 80 are ...

  8. Body surface area - Wikipedia

    en.wikipedia.org/wiki/Body_surface_area

    In physiology and medicine, the body surface area (BSA) is the measured or calculated surface area of a human body.For many clinical purposes, BSA is a better indicator of metabolic mass than body weight because it is less affected by abnormal adipose mass.

  9. International Osteoporosis Foundation - Wikipedia

    en.wikipedia.org/wiki/International_Osteoporosis...

    The International Osteoporosis Foundation (IOF), headquartered in Nyon, Switzerland, is a non-governmental organization (NGO) founded in 1998. It was formed from the merger of the European Foundation for Osteoporosis, founded in 1987, and the International Federation of Societies on Skeletal Diseases. [1]
