Factors influencing calcaneus quantitative ultrasound measurements in an urban population.
OBJECTIVE To estimate the effect of demographic, social, behavioural and anthropometric factors on quantitative ultrasound (QUS) parameters in an urban population. METHODS Cross-sectional evaluation of consecutive subjects selected as part of the EPIPorto study, Portugal. Information was obtained on demographic, social, clinical and behavioural characteristics using a standard protocol. Calca...
متن کاملInfluence of Inflammatory Polyarthritis on Quantitative Heel Ultrasound Measurements
BACKGROUND There are few data concerning the impact of inflammatory polyarthritis (IP) on quantitative heel ultrasound (QUS) measurements. The aims of this analysis were i) to determine the influence of IP on QUS measurements at the heel and, ii) among those with IP to determine the influence of disease related factors on these measurements. METHODS Men and women aged 16 years and over with r...
متن کاملCalcaneous quantitative ultrasound measurements predicts vertebral fractures in idiopathic male osteoporosis.
OBJECTIVES The aim of this study was to identify the differences in ultrasound bone variables (QUS) and to test the ability to discriminate male patients with and without vertebral fractures. METHODS We therefore measured broadband ultrasound attenuation (BUA) and speed of sound (SOS) matched for bone mineral density (BMD) and vertebral deformity in idiopathic male osteoporosis. RESULTS One...
متن کاملCorrelation between Calcaneal Bone Ultrasound Measurements and Densitometry among Postmenopausal Women with Fractures Caused by Bone Fragility.
OBJECTIVE To assess the correlation between ultrasound (US) measurement on the calcaneus and bone densitometry (DEXA), among postmenopausal women who already presented fragility fractures. METHODS 35 postmenopausal women over 40 years of age, with the ability to walk and presenting osteoporotic fractures of the wrist or spine, without previous treatment for osteoporosis, were analyzed in a re...
متن کاملCorrelations between acoustic properties and bone density in bovine cancellous bone from 0.5 to 2 MHz.
Correlations between acoustic properties and bone density were investigated in the 12 defatted bovine cancellous bone specimens in vitro. Speed of sound (SOS) and broadband ultrasonic attenuation (BUA) were measured in three different frequency bandwidths from 0.5 to 2 MHz using three matched pairs of transducers with the center frequencies of 1, 2.25, and 3.5 MHz. The relative orientation betw...
