Background: Quantitative ultrasonography of the proximal phalanges of the hand (QUS) has emerged as an attractive technical choice to assess bone quality features both in terms of bone mass and structure. Strong associations were found between QUS measures, chronological age and growth variables, such height, weight and pubertal stages. Aim: To evaluate the relationship between skeletal age and...

OBJECTIVE The aim of this cross-sectional cohort study is to assess the potential of quantitative ultrasound (QUS) of the calcaneus in pre-screening for vertebral/non-vertebral fractures, and in discriminating osteoporotic from normal bone density in patients with ankylosing spondylitis (AS); a second objective is to determine the prevalence of osteoporosis using dual-energy X-ray absorptiometr...

A high incidence of bone disease in patients with inflammatory bowel disease (IBD) requires frequent monitoring of skeletal status and, for that reason, evaluation of radiation-free technology is an issue of interest. Our objective was to appraise the parameters of calcaneal quantitative ultrasound (QUS): broadband ultrasound attenuation (BUA), speed of sound (SOS) and stiffness index (QUI), an...

OBJECTIVE To examine the diagnostic performance of clinical risk indices combined with quantitative ultrasound calcaneus measurement (QUS) for identifying osteoporosis in Thai postmenopausal women. MATERIAL AND METHOD The present study was designed as a cross-sectional investigation in 300 Thai women, aged between 38 and 85 years (mean age: 58). Femoral neck bone mineral density (BMD) was mea...

Objective - The aim of this study was to measure the ratio of bone cortex (C) to bone diameter (D), (C/D) in radius/tibia, metacarpus /metatarsus and proximal phalanges in fore and hindlimbs to be used as a diagnostic guide in metabolic and nutritional diseases in Minature Donkey. Design- Experimental study Animals- Eight adult Minature donkeys. Procedures- Lateromedial, dorsopalmar and dors...

To identify a proper T-score threshold for the diagnosis of osteoporosis in Koreans using quantitative ultrasonography (QUS), normative data from 240 females and 238 males (ages 20-29 yr) were newly generated. Then, the osteoporosis prevalence estimate for men and women over 50 yr of age was analyzed using previous World Health Organization (WHO) methods and heel QUS. T-scores were calculated f...

Although there are several techniques currently available to assess skeletal integrity in live birds, few offer important features for application in a commercial setting, offering ease of use and moderate cost. Quantitative ultrasonography (QUS) is an established technique for diagnosis of osteoporosis in humans and horses that has potential application for layers. An OmniSense 700S quantitati...

BACKGROUND Reduced bone mineral density (BMD) is associated with renal osteodystrophy and osteoporosis in end-stage renal failure patients. Dual-energy X-ray absorptiometry (DXA) is the standard non-invasive method to assess BMD, but is not always widely available. Quantitative heel ultrasound (QUS) is a mobile, relatively inexpensive, easy to perform and radiation-free method which can predict...

BACKGROUND Previous studies from our group have shown that a high prevalence of vertebral deformities suggestive of fracture can be found in patients with an inflammatory disease, despite a near normal bone mineral density (BMD). As quantitative ultrasound (QUS) of the heel can be used for refined assessment of bone strength, we evaluated whether QUS can be used to identify subjects with an inf...

Recent studies report reduced bone mineral density (BMD) even among young adults and children with hemophilia. Our aim was to assess bone status in children and adolescents with hemophilia with 2 methods: Quantitative UltraSonography (QUS) and Dual energy x-ray Absorptiometry (DXA), and consequently to investigate the degree of correlation between them. Twenty-seven patients (17 with severe hem...
