Peripheral Quantitative Computed Tomography (pQCT) can be used for muscle and fat area and density assessments. These may independently influence muscle and fat mass measurements from Dual Energy X-ray Absorptiometry (DXA).

Objective: To determine associations between pQCT-derived soft tissue density and area measures and DXA-derived soft tissue mass.

Methods: Linear regression models were developed based on BMI and calf fat and muscle cross-sectional area (FCSA and MCSA) and density measured by pQCT in healthy women (n=76) and men (n=82) aged 20-59 years. Independent variables for these models were leg and total bone-free lean mass (BFLM) and fat mass (FM) measured by DXA.

Results:Sex differences (p

Conclusion: Calf muscle and fat area and density independently predict lean and fat tissue mass.
