My doctor says I need to have a bone density scan. What is a bone density scan?

A bone density scan is an imaging test that measures the density of your bones. It can help doctors diagnose and treat osteoporosis, a condition in which bones become weak and brittle. The test involves taking pictures of the bone using a special X-ray machine. The images are then analyzed by a radiologist who can see if there are any areas of the bone that are thinner than normal.
