Bone Mineral Densitometry

A bone density test determines if you have osteoporosis — a disorder characterized by bones that are more fragile and more likely to break.

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 in the spine, hip and sometimes the forearm.

Doctors use bone density testing to:

• Identify decreases in bone density before you break a bone
• Determine your risk of broken bones (fractures)
• Confirm a diagnosis of osteoporosis
• Monitor osteoporosis treatment
