Total-body skeletal muscle mass:estimation by a new dual-energy X-ray absorptiometry method
Body composition nutritional assessment skeletal muscle mass magnetic resonance imaging dual-energy X-ray absorptiometry
2016/12/19
Background: Skeletal muscle (SM) is an important body-composition component that remains difficult and impractical to quantify by most investigators outside of specialized research centers. A lar...
Determination of skeletal muscle and fat-free mass by nuclear and dual-energy X-ray absorptiometry methods in men and women aged 51–84 y
bioimpedance analysis aging anthropometry
2016/6/1
Skeletal muscle mass (SMM) and fat-free mass
(FFM) are important variables in nutritional studies. Accurate
techniques for measuring these variables have not been thoroughly
validated in elderly su...
Segmental Musculoskeletal Examinations using Dual-Energy X-Ray Absorptiometry (DXA):Positioning and Analysis Considerations
Segmentation muscle bone standardisation composition regional method
2016/1/9
Musculoskeletal examinations provide informative and valuable quantitative insight into muscle and bone health. DXA is one mainstream tool used to accurately and reliably determine body composition co...
Relationship between the Bone Mineral Density of Mandible by Quantitative Computed Tomography and Lumbar Spine by Dual Energy X-ray Absorptiometry
quantitative computed tomography (QCT) mandible bone mineral density (BMD) osteoporosis periodontal disease
2009/5/27
Osteoporosis is a systemic skeletal disorder characterized by low bone mass. Periodontitis is an inflammation of the supporting tissues of the teeth, usually leading to loss of alveolar bone. The purp...
Infant feeding method and obesity: body mass index and dual-energy X-ray absorptiometry measurements at 9–10 y of age from the Avon Longitudinal Study of Parents and Children (ALSPAC)1,2,3
Avon Longitudinal Study of Parents and Children ALSPAC epidemiology
2008/12/11
Background: Previous studies reported inconsistent associations between breastfeeding and body mass index (BMI; in kg/m2). Associations with body fatness are unknown.Objective: We investigated the ass...
Interchangeability of pencil-beam and fan-beam dual-energy X-ray absorptiometry measurements in piglets and infants
fan-beam body composition piglets infants
2017/1/3
Compared with the older pencil-beam (PB) dual-energy X-ray absorptiometry (DXA), the newer fan-beam (FB) DXA has the advantage of faster scan acquisition and greater accuracy of body-composition measu...
Body fat percentages measured by dual-energy X-ray absorptiometry corresponding to recently recommended body mass index cutoffs for overweight and obesity in children and adolescents aged 3–18 y
Percentage body fat body mass index obesity dual-energy X-ray absorptiometry overweight children adolescents
2016/12/20
Background: Body mass index (BMI; in kg/m2) cutoffs for use with children and adolescents aged 2–18 y that correspond to the well-accepted BMI cutoffs for overweight (≥ 25 but < 30) and obesity (...
Body fat in neonates and young infants:validation of skinfold thickness versus dual-energy X-ray absorptiometry
Growth neonates infants body composition body fat nutrition skinfold thickness dual-energy X-ray absorptiometry
2016/12/19
Background: There is an interest in noninvasive measurement of body fat in newborns and infants. Measurement of skinfold thickness (SFT) is a simple clinical method.Objective: We correlated ...
Evaluating body fat in girls and female adolescents:advantages and disadvantages of dual-energy X-ray absorptiometry
Body fat percentage of fat mass fat-free mass girls female adolescents densitometry isotope dilution dual-energy X-ray absorptiometry 4-compartment model
2016/12/19
Background: Within the past 10 y, dual-energy X-ray absorptiometry (DXA) has become one of the most widely used methods of measuring human body composition. However, DXA has not been fully evalua...
