AIMS To establish normative data for phalangeal quantitative ultrasound (QUS) measures in Brazilian students. METHODS The sample was composed of 6870 students (3688 females and 3182 males), aged 6 to 17 years. The bone status parameter, Amplitude Dependent Speed of Sound (AD-SoS) was assessed by QUS of the phalanges using DBM Sonic BP (IGEA, Carpi, Italy) equipment. Skin color was obtained by...

INTRODUCTION Age-related bone quality measurements play a vital role in many areas of research. One area where the assessment of bone quality is essential is in impact biomechanics. This field relies heavily on whole-body cadaveric specimens to determine potential injuries and their mechanisms. It is therefore essential to determine whether bone fractures and other injuries sustained are due to...

INTRODUCTION Our objective was to evaluate longitudinally the main bone-mass and quality predictors in young juvenile idiopathic arthritis (JIA) patients by using lumbar spine dual-energy X-ray absorptiometry (DXA) scan, radius peripheral quantitative computed tomography (pQCT), and phalangeal quantitative ultrasonography (QUS) at the same time. METHODS In total, 245 patients (172 females, 73...

The goal of this study is to clarify the relationship between quantitative ultrasonic measurements (QUS), bone mineral density (BMD) and micro architectural parameters (reflecting morphology, connectivity and anisotropy) measured on human proximal femur. BMD was determined using X-ray quantitative computed tomography (QCT) and micro architecture was investigated using synchrotron radiation micr...

BACKGROUND BoneTour is a campaign conducted throughout the Italian territory for the assessment of Italian people bone status and for the prevention of osteoporosis. METHODS A total of 7305 sequential subjects of both sexes were screened, collecting clinical data through the FRAX™ questionnaire, and measuring heel bone stiffness by Quantitative Ultrasonography (QUS). The 10-year risk for hip ...

A simple experimental protocol applying a quantitative ultrasound (QUS) pulse-echo technique was used to measure the acoustic parameters of healthy femoral diaphyses of Wistar rats in vivo. Five quantitative parameters [apparent integrated backscatter (AIB), frequency slope of apparent backscatter (FSAB), time slope of apparent backscatter (TSAB), integrated reflection coefficient (IRC), and fr...

The aim of this study was to investigate the relationships between selected quantitative ultrasound (QUS) parameters and human femur microstructure properties, as quantified by micro-computed tomography (micro-CT). The authors employed an innovative custom-designed experimental set-up, which allowed the insonification of each portion of an excised femoral head sample, simultaneously including t...

The purpose of this study was to investigate the association between coffee consumption and bone status (bone mineral density and bone metabolism-related markers) according to calcium intake level in Korean young adult males. Healthy and nonsmoking males (19-26 years, n = 330) participated in this study. Anthropometric measurements, dietary habits, and nutrient intakes were surveyed. Bone statu...

Skeletal imaging techniques have become clinically valuable methods for measuring and assessing bone mineral density in children young people. Dual-energy X-ray absorptiometry (DXA) is the current reference standard evaluating density, as recommended by International Society Clinical Densitometry (ISCD). Various modalities, such quantitative ultrasound (QUS), peripheral computed tomography (pQC...

AIM The relationship between bone mineral density (BMD), age and dental caries has been studied. Quantitative ultrasonography (QUS) is an economic, non invasive, and reproducible method for measuring both bone mineral density and bone elasticity in growing subjects in large populations. METHODS This study evaluated the relationship between BMD and prevalence of dental caries (Decayed Missing ...
