DEXA (Dual Energy X-ray Absorptiometry) is recognized as the standard for measuring bone mineral density (BMD). DEXA is most often performed on the lower spine and hips, unless a prosthesis is present in the hip or lower spine. When prosthesis is present in either area a scan of the forearm will be performed and analyzed.
DEXA scans are also capable of providing one of the most highly accurate measurements of body composition available, registering fat and lean mass distribution throughout the entire body. In simple terms, it is capable of detailing overall, as well as regional, fat mass, lean mass, and bone mass.
