Bone Density Scanning
A bone density test determines if you have osteoporosis — a disease that causes bones to become more fragile and more likely to break.
In the past, osteoporosis could be detected only after you broke a bone. By that time, however, your bones could be quite weak. A bone density test makes it possible to know your risk of breaking bones before the fact.
A bone density test uses X-rays to measure how many grams of calcium and other bone minerals are packed into a segment of bone. The bones that are most commonly tested are located in the spine, hip and forearm. Here at Healthy Lifestyles, an X-ray is taken of a single bone in a finger.
