Which body composition method involves using X-ray technology?

The method that involves using X-ray technology is Dual-Energy X-ray Absorptiometry (DEXA). DEXA scans utilize two different X-ray beams to measure bone mineral density as well as body composition, including fat and lean mass. It provides precise measurements of body fat percentage and distribution across different areas of the body, which makes it a highly accurate method for assessing body composition compared to other techniques.

Other methods, such as bioelectrical impedance analysis, skinfold measurements, and underwater weighing, do not employ X-ray technology. Bioelectrical impedance analysis measures the resistance of body tissues to electrical currents to estimate body composition. Skinfold measurements involve calipers to assess the thickness of skinfolds at specific sites to infer body fat percentage, while underwater weighing determines body density based on water displacement. Each of these methods has its own limitations and accuracy levels compared to the comprehensive insights offered by DEXA.
