Interpretation of Dual-Energy X-Ray Absorptiometry-Derived Body Composition Change in Athletes: A Review and Recommendations for Best Practice

Dual-energy X-ray absorptiometry (DXA) is a medical imaging technology that uses 2 X-ray beams of different energies that are diversely attenuated by bone and soft tissue. Although the primary application of DXA has historically been for osteoporosis assessment using bone mineral density (1), there has been a rapid growth in its application for the measurement of fat and lean soft tissues over the last 2 decades. This largely followed the introduction of fan beam densitometers with quicker scan acquisition times, better image resolution and quality, and lower radiation exposure.
