Bone Density Tests (also called densitometry or DEXA scans)

Bone Density Tests (also called densitometry or DEXA scans) use X-rays to measure how much calcium and other bone minerals are present in a segment of bone. The test can determine whether you have osteoporosis or are at risk for it before you break any bones. Preventive measures, including weight-bearing exercise, calcium, vitamin D supplements and prescription medication can then be taken.
