Bone mineral density(BMD) is related to bone strength. BMD testing is used to diagnose osteoporosis. BMD is measured with a test called a DXA scan. By measuring BMD, doctors can predict the risk of having a bone fracture.
A bone density scan can detect thinning bones at an early stage. If you already have osteoporosis, bone scans can also tell you how fast the disease is progressing.
But an abnormal bone scan can create as many questions as it answers. Who should get a bone density scan, and what do the results mean? If your bone density is below normal, what can you expect, and what should you do?
