Dual-energy X-ray absorptiometry (DEXA) determines which of the following body composition components that cannot be determined by other commonly used methods?

Question

Quizplus · Accepted Answer

DEXA is primarily used to measure bone density, which cannot be accurately determined through other commonly used body composition methods. While DEXA can also estimate fat and fat-free mass, these can be measured using other methods such as bioelectrical impedance analysis or skinfold thickness measurements. Total body water can be estimated through methods such as bioelectrical impedance analysis or dilution techniques using deuterium or tritium.
