      A DEXA Scan (Dual Energy X Ray Absorptiometry) scan is a special non invasive form of imaging that measures bone density and loss. In general the denser the bone, the stronger it is and therefore less likely it is to break. A DEXA scan uses low energy x-rays. The amount of x-rays that comes through the

      What is a bone density (DEXA) scan? A bone density scan uses a special type of X-ray called dual energy X-ray absorptiometry (DEXA). The scan is done on the lower back (lumbar spine), hips and sometimes the lower half of the arm (forearm). These areas are better at showing bone ageing on DEXA scans.
