DXA - A method that measures the amount of calcium and other minerals in a bone by passing X-rays through the bone at two different energy levels. A DXA shows the strength and thickness of a bone and is usually done on the lower spine, hip, forearm, wrist, fingers and heel. It is used to diagnose osteoporosis (a disease with reduced bone density), to see how well osteoporosis treatments are working and to predict how likely bones are to break. A DXA also measures fat and muscle composition in specific body parts, such as the arms, legs, and pelvis. Also referred to as a BMD scan, bone densitometry, bone mineral density scan, DEXA scan, and dual-energy X-ray absorptiometry
