Bone Density Lab and Patient Information | Bone and Mineral Clinic

The Bone Density Lab uses Dual Energy X-ray Absorptiometry (DXA) to measure the mineral density of bones. A bone density scan can help provide important information to you and your physician for the diagnosis, treatment and monitoring of osteoporosis and other metabolic bone conditions.

Metabolic bone disorders, like osteoporosis, are characterized by a loss of mineral and strength. Using DXA 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.

To schedule a DXA scan, call 503 494-4814.

FAQs

Who can get a DXA?

Our DXA clinics scan infant, pediatric and adult patients. A referral from your provider is required to schedule.

Why should I have a DEXA 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.

What happens during a bone density measurement?

The DEXA test is painless. You lie on a table while the machine scans your spine, hip, or other sites. Your visit takes about 20 minutes. A bone density measurement of your forearm may be necessary. For this scan, you sit in a chair while the machine scans your forearm. This takes about 5 minutes.

How does DEXA work?

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.

Does medical insurance cover the cost of the scan?

Most medical insurance companies typically provide coverage for this procedure, but coverage is not limited to osteoporosis. Contact your insurance company to confirm coverage for CPT 77080.

When should I delay a bone density measurement?

  • If temporarily unable to lie flat
  • You should not have a bone density measurement within 10 days of having any of the following tests:
    • Bone scan
    • Angiogram
    • CAT scan with contrast
    • Myelogram
    • Nuclear cardiology testing
    • PET scan
    • Barium testing
    • Bone Scan/Nuclear Medicine

How should I prepare for my DEXA measurement?

  • Please complete the Bone Density Survey in MyChart prior to your appointment.
  • Refrain from taking Calcium the day of your appointment.
  • No Nuclear Medicine or imaging contrast 7-10 days prior to Bone Density appointment.
  • Wear loose clothing without zippers, snaps, buckles, reflective or other metallic material and undergarments without wires. We can provide a gown.
  • Remove jewelry, metal objects, and body piercings over the spine, hips, and arms.
  • Leave jewelry and other valuable items at home.

What happens after the scan?

A specialist will review the test results and send them to your physician, who will give you the results.
