A DEXA scan uses a very low dose of X-rays to measure your bone density. You lie still on a padded table in everyday clothes, as long as nothing has metal in it, while a scanning arm passes slowly over you.
Bone density scanning is established care for osteoporosis screening at the ages guidelines set. The same scan can also split your weight into fat, lean tissue and bone, and many people use that part as a baseline to track as they train or change how they eat.
