Quantitative ultrasound bone measurements : normal values and comparison with bone mineral density by dual x-ray absorptiometry
TLDR
Normative data for qualitative ultrasound measurements: speed of sound (SOS), broadband ultrasound attenuation (BUA), and stiffness were established in 118 healthy women aged 20–86 years and in 42 healthy men aged 22–76 years and the relations between age, weight, height, and QUS were studied.Abstract:
Normative data for qualitative ultrasound (QUS) measurements: speed of sound (SOS), broadband ultrasound attenuation (BUA), and stiffness were established in 118 healthy women aged 20-86 years and in 42 healthy men aged 22-76 years. The relations between age, weight, height, and QUS were studied. QUS measurements were negatively correlated with age in both sexes. In women, age was accepted as first factor (R2 = 0.39 for SOS, 0.35 for BUA, and 0.45 for stiffness, P < 0.001); weight was accepted as second factor for BUA (R2 = 0.44, P < 0.001). In men, age was the only significant parameter (R2 = 0.41 for SOS, 0.39 for BUA, 0.43 for stiffness, P < 0.001). QUS measurements of the right and left feet were highly correlated unless unilateral foot pathology such as algodystrophy was present. Significant correlations were found between QUS of the calcaneus and dual X-ray absorptiometry (DXA) of the lumbar spine (R = 0.67, P < 0.01 for SOS; R = 0.57, P < 0.02 for BUA; R = 0.65, P < 0.01 for stiffness).read more

Quantitative ultrasound techniques for the assessment of osteoporosis : Expert agreement on current status
TL;DR: Evidence supports the use of QUS techniques for the assessment of fracture risk in elderly women and best established for water‐based calcaneal QUS systems, while future studies should include the predictive validity of other Q US systems.

TL;DR: This study examined the commonly available methods of noninvasively assessing bone mineral status across three defined female populations to examine their interrelationships, compare their respective abilities to reflect age‐ and menopause‐related bone loss, discriminate osteoporotic fractures, and classify patients diagnostically.

TL;DR: Although only moderately correlated with BMD, QUS appears to be as strong a predictor of osteoporotic fracture as BMD and may predict fracture independent of BMD.

TL;DR: Although the precision is variable, the calcaneal QUS and SEXA instruments can discriminate between osteoporotic patients and young normal controls and appear to be a useful technique for assessment of osteoporeosis.

TL;DR: All the QUS devices gave similar, statistically significant hip fracture discrimination for both SOS and BUA measures, and within the limitation of the sample size all devices show similar diagnostic sensitivity.

Differential changes in bone mineral density of the appendicular and axial skeleton with aging: relationship to spinal osteoporosis.
TL;DR: Bone mineral density was measured in vivo at the lumbar spine (predominantly trabecular bone) by dual photon absorptiometry and at the midradius (greater than 95% cortical bone) and distal radius (75% cortical and 25% trabECular bone), by single photon absorptioniometry as mentioned in this paper.

TL;DR: The orthotropic elastic coefficients and the variation of these coefficients are presented as a function of anatomical position and the elastic properties of human and canine cortical femora are presented here.

The measurement of broadband ultrasonic attenuation in cancellous bone.
TL;DR: The frequency dependence of ultrasonic attenuation in the range 0.2–1 MHz in in vitro samples of bovine cancellous bone and in vivo os calcis heel bones indicates that the technique allows determination of bone loss and the study of the onset and progress of osteoporosis.

TL;DR: Ultrasound velocity measures both bone mass and a component of bone fragility distinct from decreased mass; it is a potentially valuable new tool for evaluating women for osteoporotic fragility.

TL;DR: The results of this pilot study suggest that ultrasound attenuation, a safe, simple, and radiation-free procedure, may be utilized as an indicator of decreased axial bone mass.
