Bone Densitometry (DXA) Scan

A bone density test also called densitometry or DXA scandetermines whether you have osteoporosis or are at risk of osteoporosis.

Osteoporosis is a disease that causes bones to become more fragile and more likely to break.

In the past, osteoporosis could only be detected 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. A bone density test is a fairly accurate predictor of your risk of fracture.

This test is done by your medical doctor.
