  2. Dual-energy X-ray absorptiometry - Wikipedia

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

    Bone densities are often given to patients as a T score or a Z score. A T score tells the patient what their bone mineral density is in comparison to a young adult of the same gender with peak bone mineral density. A normal T score is -1.0 and above, low bone density is between -1.0 and -2.5, and osteoporosis is -2.5 and lower.

  3. Quantitative computed tomography - Wikipedia

    en.wikipedia.org/wiki/Quantitative_computed...

    The trabecular bone has much higher metabolic activity than the cortical bone and so is affected by age, disease and therapy-related changes earlier and to a greater degree than cortical bone. This means that QCT of the spine has an advantage compared to other bone density tests because earlier changes in bone mineral density may be detected .

  4. 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. [1]

  5. Dual X-ray absorptiometry and laser - Wikipedia

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

    N01 and N02 are the detected x-ray counts taken from the internal phantom. tb, ts and tf are the thickness of bone (b), lean soft tissue (s) and adipose tissue (f), respectively. T is the total thickness at the measuring point. νb1, νs1 and νf1 are the x-ray attenuation coefficients for each component at the low x-ray energy level.

  6. Trabecular bone score - Wikipedia

    en.wikipedia.org/wiki/Trabecular_bone_score

    The trabecular bone score is a measure of bone texture correlated with bone microarchitecture and a marker for the risk of osteoporosis. Introduced in 2008, [ 1 ] its main projected use is alongside measures of bone density in better predicting fracture risk in people with metabolic bone problems.

  7. Bone health - Wikipedia

    en.wikipedia.org/wiki/Bone_health

    Bone mineral density (BMD) is a measure commonly used to quantify bone health. A lower BMD value indicates an increased risk of an osteoporosis or a fracture. [13] There is a large range of factors influencing BMD. Protein consumption has shown to be beneficial for bone density by providing amino acid substrates necessary for bone matrix formation.

  8. FRAX - Wikipedia

    en.wikipedia.org/wiki/FRAX

    FRAX integrates clinical risk factors and bone mineral density at the femoral neck to calculate the 10-year probability of hip fracture and the 10-year probability of a major osteoporotic fracture (clinical spine, forearm, hip or shoulder fracture). [2]
