Bone Densitometry
DEXA/DXA = Bone Densitometry
Dexa measures the density of the spine and hip.
Dexa is the gold standard for measuring bone density and diagnosing osteoporosis and osteopenia as well as for monitoring the response to medication therapy for these disorders. It uses very low doses of radiation (1/10th the radiation of a chest x-ray).
Dexa is a non-invasive test and only requires the patient to be positioned lying on a cushioned table while it measures the density of the spine and hip. The scan itself approximately takes 10 to 15 minutes, but you should allow 30 minutes in all. It has been recommended as a screening test for all women over 65 years of age, and for all men over 70 by the International Society of Clinical Densitometry, The National Osteoporosis Foundation, the U.S. Preventive Service Task Force, and other organizations as well as the Surgeon General.
Repeat Dexa scans are recommended every 2 or more years, however if patient is on a steroid treatment or other risk factors, scans maybe repeated more frequently.

Frequently Asked Questions:
- How much radiation will I be exposed to?
- Answer: You will be exposed to minimal radiation. ie: similar to a coast-to-coast plane ride.
- Is the test invasive?
- No, nothing needs to be taken orally or intravenously.
- What does the test measure?
- It measures the density and strength of your bones and can help your doctor estimate for any future risk fractures.
- Do I need prepare for the test?
- You do not need to fast, however you should not take calcium supplements 24 hours before the test.
- How and when will I get my test results?
- Your doctor will receive your results within 3-5 business days.
