Comparison of ten predictive equations for estimating lean body mass with dual-energy X-ray absorptiometry in older patients.

ABSTRACT:

Objectives

White fat contributes to body weight (BW) but accumulates very little [¹⁸F]fluorodeoxyglucose ([¹⁸F]FDG) in the fasting state. As a result, higher standardised uptake values normalised to BW (SUV) are observed in non-fatty tissue in obese patients compared to those in non-obese patients. Therefore, SUV normalised to lean body mass (SUL) that makes tumour uptake values less dependent on patients' body habitus is considered more appropriate. This study aimed to assess ten mathematical equations to predict lean body mass (LBM) by comparison with dual-energy X-ray absorptiometry (DXA) as the reference method.

Methods

DXA-based LBM was compared with ten equation-based estimates of LBM in terms of the slope, bias and 95% limits of agreement (LOA) o
