Bone loss leads to increase risk of fractures in renal transplantation. The aim this study was analyse the relationship between bone densitometry (DXA) findings, histomorphometry and bone-related molecules 1-year after We performed a cross-sectional de novo transplanted patients that agreed perform biopsy DXA examination 1 year All underwent laboratory evaluation, biopsy, cardiac CT 67 were inc...

Bio-electrical impedance analysis (BIA) and dual-energy X-ray absorptiometry (DXA) are methods to estimate human body composition. This study aimed compare sex-specific outcomes for estimating segmental whole-body composition in 83 healthy participants (21.9 ± 1.5 years, 56% men) using Inbody S10 BIA Norland Elite DXA devices. One-way repeated measures ANOVAs showed significantly lower fat% fat...

Today, QCT is one of three methods, including DXA, cited by the National Osteoporosis Foundation as safe and effective for the evaluation of BMD[3]. The QCT system comprises a CT scanner calibration device and a software application on a standalone Windows PC networked to the CT scanner. At the hip, QCT produces BMD T-Score measurements that are clinically equivalent to DXA measurements[5], but...

BACKGROUND AND AIMS Children with Crohn disease are at increased risk for osteopenia and osteoporosis. Early development of osteopenia can increase the lifetime risk for fractures and may be amenable to early intervention. The gold standard for measuring bone mineral density (BMD) and fracture risk is dual x-ray absorptiometry (DXA), but this involves some radiation and specialized programs for...

Expanding medical knowledge increases the potential risk of medical errors in clinical practice. We present, OPAD, a clinical decision support system in the field of the medical care of osteoporosis. We utilize clinical information from international guidelines and experts in the field of osteoporosis. Physicians are provided with user interface to insert standard patient data, from which OPAD ...

Dual-energy X-ray absorptiometry (DXA) is a novel, non-invasive technique for the measurement of gross body composition in small animals. In the present study the absolute accuracy of the Hologic QDR-1000W scanner was assessed by comparison with direct analysis in twelve rats with a range of body fat and bone mineral content (BMC) values. Fat masses measured by DXA and petroleum-ether extractio...

Dual-energy X-ray absorptiometry (DXA) percent (%) fat estimates may be inaccurate in young children, who typically have high tissue hydration levels. This study was designed to provide a comprehensive analysis of pediatric tissue hydration effects on DXA %fat estimates. Phase 1 was experimental and included three in vitro studies to establish the physical basis of DXA %fat-estimation models. P...

Non-invasive measurement of body composition provides advantages in growth studies compared to conventional techniques. The same individual can be measured several times, the measurement is faster, and the number of pigs required as well as the random effect of animal are reduced. The aim of the present study was to determine the composition of the half carcass and of the ham/shank region by a ...

Human immunodeficiency virus (HIV)-infected patients have an increased risk of developing osteopenia or osteoporosis compared with healthy individuals. Our aim was to compare dual X-ray absorptiometry (DXA), the gold standard for measuring bone mineral density (BMD), with bone quantitative ultrasound (QUS), an alternative technique for predicting fractures and screening low BMD, at least in pos...
