Summary: This study aimed to assess the relationship between bone mass and lean mass (LM) and fat mass (FM) in normal-weight and overweight adolescents. The results showed that only LM was associated with bone mass in both normal-weight and overweight adolescents. LM was found to be the main predictor of bone mass in these groups.

Summary: The study investigated the precision of DXA detection in cynomolgus monkeys and identified the difference in precision in lumbar bone mineral density with various segment selections. Results showed excellent reproducibility of DXA measurements in nonhuman primates, making it a reliable tool for total and regional measurement in skeletal research and evaluation of osteoporosis treatment with monkeys as animal models.

Summary: BatchBMD is a rule-based automated reporting system that accelerates the generation of DXA reports and improves accuracy. Compared to a Web-based reporting system, BatchBMD outperforms in reporting time and accuracy, significantly reducing workload for radiologists and technicians.

Summary: Studies in animal science show that DXA measurements may not perfectly match dissections or chemical analyses, requiring calibration equations. Predictions related to body composition and single nutrient content in pigs show promising results, with potential for creating generic regression equations that yield reliable estimates. DXA could be a useful tool for high-throughput phenotyping in genetic studies, efficiently measuring body composition in a wide range of animals.

Summary: The study investigated the feasibility of slot-scan dual-energy bone densitometry on motorized radiographic equipment for fast quantitative measurements of areal bone mineral density. Results showed accurate and reproducible aBMD measurements across different body sizes and positioning with small errors. Empirical evaluations confirmed the reduction in aBMD errors with proposed procedures on robotic x-ray systems.

Summary: This study examines the unique measurement and quality-control strategies in dual-energy X-ray absorptiometry (DXA) and analyzes the dependence of measured entrance-air-kerma (EAK) on dose sensor type and scan length. The feasibility of using EAK to compare scanner output and the congruence between measured and vendor-reported EAK were also established. The results suggest that DXA scanner stability can be quantified using EAK as a quality-control metric with a variety of solid-state and ion chamber (IC) dose sensors. Measured EAK may vary significantly between different scanners, indicating that measured and reported EAK may not always be comparable.

Summary: In this study, the authors assessed the diagnostic discordance between lumbar osteoporosis detected by QCT and DXA, and evaluated their predictive performance for prevalent vertebral fracture. The results showed that in older patients undergoing spinal surgery, QCT-vBMD is more helpful than DXA in terms of osteoporosis detection rate and prediction of patients with prevalent VFs.

Summary: The study evaluated the feasibility of using DECT and CT values for opportunistic screening of osteoporosis in postmenopausal females. The results showed a moderate-high correlation between HAP and CT value with DXA measurements for diagnosing osteoporosis. The cutoff values of HAP and CT value for diagnosing osteoporosis were determined to be 142.05 mg/cm3 and 132 HU, respectively.

Summary: This study assessed the prevalence and clinical characteristics of osteoporosis in Chinese patients with PBC. The results showed that osteoporosis is very common in PBC patients, with older age, lower BMI, previous steroid therapy, and advanced liver disease being the main independent risk factors.

Summary: This study aims to evaluate body composition and its relationship with hormonal control in acromegaly, comparing the effectiveness of Bioelectrical impedance analysis (BIA) with dual X-ray absorptiometry (DXA), which is commonly used in current studies. The results show that there were no significant differences in body composition between patients with controlled and active disease. In patients with adequate hormonal control, there was preservation of muscle mass and a lower prevalence of metabolic comorbidities, such as type 2 diabetes (T2D) and high blood pressure (HBP).

Summary: This study found that in CKD patients, those on dialysis had lower CortBMD and cortical mineral content Z-scores, and DXA measurements were not predictive of bone density. Biomarkers PTH, ALP, and Ca were moderate predictors of CortBMD, with DXA not improving the predictive model.
