"Bone densitometry" means a noninvasive measurement of certain physical characteristics of bone that reflect bone strength. Test results are typically reported as bone mineral content or density and are used fordiagnosing osteoporosis, estimating fracture risk, and monitoring changes in bone mineral content.
