DXA – or sometimes DEXA – scans are important for people in their 60s and above. They are also increasingly used by younger people interested in body composition.
A DXA – dual-energy X-ray absorptiometry – scan is an imaging test that uses low-dose X-rays to evaluate a person’s bone health, explains Dr Michael Perry, associate professor of radiology and medical imaging at the University of Virginia’s school of medicine. Most often, DXA scans are used to measure the strength and mineral content of an individual’s bones. This in turn helps determine that person’s risk of osteoporosis and bone fractures.
