Overview

DXA (dual-energy X-ray absorptiometry) is a low-radiation scan that measures bone mineral density, often at the hip and spine. It helps diagnose osteoporosis/osteopenia and refine fracture risk estimates. DXA is used for screening in higher-risk groups and for follow-up to track bone density over time.

Who Should Get This Screening

Older adults or people with higher fracture risk (risk-based).
People with a fragility fracture or long-term steroid use are often candidates for earlier testing.
Postmenopausal people and older men are commonly screened based on age and risk factors (clinician-guided).

What to Expect

You lie on a padded table while the scanner passes over you. The test is painless, and you remain still while images are taken.

How to Prepare

Follow these tips to prepare for your screening

Wear clothing without metal (zippers/buttons) near the scan area when possible.
Some clinics advise avoiding calcium supplements for 24 hours beforehand.
Tell staff if you recently had contrast imaging (CT/barium) or could be pregnant.

Benefits

Diagnoses osteoporosis early.
Guides treatment decisions to reduce fracture risk.
Very low radiation exposure.

Things to Consider

Very low radiation exposure.
Results can be affected by spinal arthritis or positioning; interpretation matters.
