Bone Density (DEXA) Scan
Metabolic bone disorders, like osteoporosis, are characterized by a loss of mineral and strength. Using Dual Energy X-ray Absorptiometry (DEXA) to measure the mineral density in a variety of bones can help provide important information to you and your physician for the diagnosis, treatment and monitoring of Osteoporosis and other metabolic bone conditions.

FAQ's - Bone Density Measurement
Various conditions, including simply aging, may increase the risk of osteoporosis. DEXA can help provide important information to you and your physician for the diagnosis, treatment, and monitoring of osteoporosis. Other bone measurements (for example, ultrasound performed on the heel) can also be used to detect osteoporosis, but DEXA scanning provides the most useful information.
Most medical insurance companies, including Medicare, typically provide coverage for this procedure but coverage is not limited to osteoporosis. This procedure typically is covered for use in treating hypogonadism, chronic liver and renal disease, hyperparathyrodism and hyperthyroidism, prolonged glucocorticoid therapy, rheumatoid arthritis, and malabsorptive disorders.
The DEXA machine uses a small amount of X-ray to measure the amount of
mineral in the bones. It provides information that is different from
regular X-rays, which show the shape and structure of bones. The amount
of X-ray you are exposed to is the same as one day of natural background
exposure, or about the same amount of radiation you might be exposed to
during a cross-country plane trip.
The DEXA test is painless. You lie on a table or sit in a chair while the scanner scans the prescribed area(s). Your visit will take approximately 20 minutes or less.
- Bone scan
- CAT scan with contrast
- Nuclear cardiology testing
- Wear clothing that is comfortable and easy to remove. You may be asked to change into a gown before the scan.
- On the day of your appointment, do not take calcium supplements before the scan.
- You will be asked to lie on a table on your back for five to 10 minutes.
A specialist will review the test results and send them to your physician, who will give you the results.
