TLDR
There was high agreement between all DXA systems for estimation of BMC and body composition, and cross-calibration equations should be used to examine data across systems to avoid erroneous conclusions.About:

TL;DR: An emphasis is placed on low muscle strength as a key characteristic of sarcopenia, uses detection of low muscle quantity and quality to confirm the sarc Openia diagnosis, and provides clear cut-off points for measurements of variables that identify and characterise sarc openia.

TL;DR: The aim of this study was to review the methods to assess muscle mass and to reach consensus on the development of a reference standard for measuring lean body mass.

The impact of recent technological advances on the trueness and precision of DXA to assess body composition
TL;DR: The evidence regarding the trueness and precision of DXA body composition measurements from the pencil‐beam to the narrow fan‐beam densitometers is reviewed.
Journal ArticleDOI
Why are there race/ethnic differences in adult body mass index-adiposity relationships? A quantitative critical review.
TL;DR: This work systematically review the magnitude of these race‐ethnic differences across non‐Hispanic (NH) white, NH black and Mexican American adults, their anatomic body composition basis and potential biologically linked mechanisms, using both earlier publications and new analyses from the US National Health and Nutrition Examination Survey.

Methodology review: using dual-energy X-ray absorptiometry (DXA) for the assessment of body composition in athletes and active people
TL;DR: A summary of the sources of error and variability in the measurement of body composition by DXA is presented, and a theoretical model of best practice to standardize the conduct and analysis of a DXA scan is developed.

Dual-energy x-ray absorptiometry for total-body and regional bone-mineral and soft-tissue composition.
TL;DR: Bone mineral density (BMD) and soft-tissue composition of the total body and major subregions were measured with dual-energy x-ray absorptiometry (DEXA) and there were no significant differences in mean results or in precision errors between the two speeds.

Larger Amounts of Visceral Adipose Tissue in Asian Americans
TL;DR: These data are the first to demonstrate higher amounts of VAT in healthy Asian Americans, a finding that suggests normative VAT values or standards derived from whites may not be applicable to Asians.

Quantitative digital radiography versus dual photon absorptiometry of the lumbar spine.
TL;DR: Quantitative digital radiography's image resolution was superior to that of DPA, enabling it to measure more bones, and the elimination of 153Gd source changes and Nuclear Regulatory Commission licensing requirements indicate that quantitativedigital radiography is the superior method for spinal BMD measurements.

Femoral-gluteal subcutaneous and intermuscular adipose tissues have independent and opposing relationships with CVD risk.
TL;DR: Femoral-gluteal SAT and femoral- gluteal IMAT distribution varies by sex and race, and these two components have independent and opposing relationships with CVD risk factors.

Dual X-ray absorptiometry: a comparison between fan beam and pencil beam scans
TL;DR: In this paper, the effect of the change in beam configuration on dual X-ray absorptiometry (DXA) measurements acquired on one of the new generation scanners, the Hologic QDR-2000, were compared with scans performed on an earlier pencil beam model.
