Relationship Between Dual Energy X Ray Absorptiometry Dxa Lean Mass

Relationship Between Dual Energy X Ray Absorptiometry Dxa Lean Mass Representative dxa scan. a visual representation of fat mass, lean body mass and bone mass is shown for a participant (a) before treatment and (b) at the week 49 visit.cutlines are placed on the. Dual energy x ray absorptiometry (dxa) derived measures of lean mass demonstrate strong associations with magnetic resonance imaging (mri) derived measures of muscle volume (mv) in cross sectional.

Relationship Between Dual Energy X Ray Absorptiometry Dxa Lean Mass Dual energy x ray absorptiometry (dxa) is a validated technique to assess body composition. it is well known that the relationship between obesity and reference standards for lean mass. We only included studies reporting the association between all cause mortality and muscle mass measured by computerized tomography (ct), dual energy x ray absorptiometry (dxa) or bioelectrical impedance analysis (bia) reported as “reduced lean mass” (ie, lean mass was treated as continuous variable) or “low lean mass” (ie, lean mass was treated as a binary variable, low vs normal lean. Introduction. in 2017, dual energy x ray absorptiometry (dxa) celebrated its 30 th anniversary ().since the initial development of this technique as the successor of dual photon absorptiometry, dxa technology assisted to continuous technological innovations and is now widely considered as the standard of reference in assessing bone mineral density (bmd) and fracture risk (). Lm measured by dual energy x ray absorptiometry (dxa) is a composite of non fat and non bone tissue and is highly associated with lm measured using ct and mri technology (r 2 = 0.86–0.96) [4–6]. dxa is also less expensive and time consuming than ct and mri scans, and therefore is considered the best alternative method for measuring lm [ 4 , 7 ].
