PMID: 39772583
CT-based abdominal body composition measures have shown associations with important health outcomes. Advances in artificial intelligence (AI) now allow deployment of tools that measure body composition in large patient populations....

PMID: 39761492
Objective: Computed tomography (CT) measured muscle density is prognostic of health outcomes. However, the use of intravenous contrast obscures prognoses by artificially increasing CT muscle density. We previously established a...

PMID: 37732694
Purpose: Intravenous contrast poses challenges to computed tomography (CT) muscle density analysis. We developed and tested corrections for contrast-enhanced CT muscle density to improve muscle analysis and the utility of...

PMID: 36364934
β-Hydroxy-β-methylbutyrate (HMB), a leucine metabolite, can increase skeletal muscle size and function. However, HMB may be less effective at improving muscle function in people with insufficient Vitamin D3 (25-OH-D <...

PMID: 36065509
Computed tomography (CT) is a valuable assessment method for muscle pathologies such as sarcopenia, cachexia, and myosteatosis. However, several key underappreciated scan imaging parameters need consideration for both research and...

PMID: 34368612
Traditional diagnostic criteria for sarcopenia use dual-energy X-ray absorptiometry (DXA)-measured appendicular lean mass (ALM), normalized to height (ALM/ht) or body mass index (ALM/BMI) to define low muscle mass. However, muscle...

. 2018 Sep;
13(1):97.
PMID: 30218261
Rationale: Fluid volume estimates may help predict functional status and thereby improve sarcopenia diagnosis. Main Result: Bioimpedance-derived fluid volume, combined with DXA, improves identification of jump power over traditional measures....
