Summary
Bone densitometry is a simple and quick scan used to determine a patient’s bone density. Specifically, it measures bone minerals (calcium) and bone density to determine if the patient has osteoporosis – a condition in which bones have lost minerals, especially calcium - and to monitor patient reactions to osteoporosis treatment.
Who should have a bone densitometry scan?
- All women age 65+
- Women who are postmenopausal, under age 65, with one or more additional osteoporosis risk factors (see below)
- Women who are postmenopausal who have suffered fractures
- Women who either are or have been on hormone replacement or estrogen replacement therapy for prolonged periods
- Women considering therapy for osteoporosis who want a scan to facilitate the decision
