Implication

Validation study demonstrates that bioimpedance modeling accurately estimates lower limb muscle volume in lean adults, indicating a reliable alternative to magnetic resonance imaging.

Key Points

To determine whether a three-dimensional electrical bioimpedance model can accurately predict lower extremity muscle distribution and volume compared with magnetic resonance imaging.
Constructed a 3D lower limb model by segmenting MRI scans into adipose tissue, skeletal muscle, and bone, and assigned an electrical network assuming muscle longitudinal conductivity of 0.85 S/m.
Acquired bioimpedance analysis (BIA) and MRI cross-sectional measurements from six lean individuals (3 men, 3 women; mean age 32.2 ± 6.9 years).
Compared predicted electrical resistance profiles, cross-sectional muscle areas, and total leg muscle volumes directly against empirical MRI benchmarks.
Predicted electrical resistance closely matched measured resistance values (261.3 ± 7.7 vs. 249 ± 9 Ω; P = not significant).
The model estimated lower limb muscle volume (mean 4,534 cm³ in men and 4,071 cm³ in women) with a mean absolute relative error of 6.2 ± 3.9% relative to MRI.
