A DEXA scan — or bone densitometry — is one of the most reliable tools for measuring bone strength and detecting osteoporosis. Sheridan Memorial Hospital offers quick, comfortable DEXA imaging to help you understand your bone health and reduce your risk of fractures as you age.
Whether your provider has recommended testing or you’re simply wanting a clearer picture of your long-term health, a DEXA scan provides valuable information for protecting your bones and maintaining an active lifestyle.
What Is a DEXA Scan?
A DEXA scan (Dual-Energy X-ray Absorptiometry) uses two low-dose X-ray beams to measure the density of your bones. It is a safe, painless imaging test that assesses bone strength — most commonly in the hip, spine, and sometimes the forearm, where fractures are most likely to occur.
DEXA is considered the best method for diagnosing osteoporosis and assessing fracture risk.
The radiation exposure is extremely low — much lower than a standard chest X-ray — making it safe for routine monitoring.
Why You Might Need a DEXA Scan
Your healthcare provider may recommend a bone density test for several reasons, including:
- Age & Preventive Screening
-
Women aged 65+
-
Men aged 70+
-
Postmenopausal women under 65 with risk factors
-
- Medical Risk Factors
-
History of fractures or bone loss
-
Long-term use of steroids (like prednisone)
-
Early menopause or surgical removal of ovaries
-
Low body weight or a family history of osteoporosis
-
Certain medical conditions (thyroid disorders, rheumatoid arthritis, digestive diseases)
-
- Lifestyle Factors
-
Smoking
-
Low calcium or vitamin D intake
-
Little or no physical activity
-
- Monitoring Treatment
- If you’ve been diagnosed with osteoporosis or osteopenia, a DEXA scan helps your provider monitor whether treatment is working.
What to Expect During Your DEXA Scan
A DEXA scan is one of the easiest imaging tests you can have—no injections, no contrast dye, and no enclosed spaces.
- Before Your Scan
-
Wear comfortable clothing without metal zippers, snaps, or buttons.
-
Avoid calcium supplements for 24 hours before your test (unless instructed otherwise).
-
Your technologist will review your medical history, previous fractures, and medications.
-
- During the Scan
-
You’ll lie comfortably on a padded table while the scanning arm slowly moves over your body.
-
The test is completely painless and usually takes 5-10 minutes.
-
You’ll be able to breathe normally and remain relaxed throughout the exam.
-
- After the Scan
-
You can resume your normal activities immediately.
-
A radiologist will analyze your bone density measurements and send results to your provider.
-
Your doctor will discuss your “T-score,” which indicates whether your bone density is normal, low (osteopenia), or in the osteoporosis range.
-
The Importance of Early Detection
Osteoporosis often has no symptoms until a fracture occurs. A DEXA scan allows early detection, so you and your provider can take steps to strengthen your bones through lifestyle changes, supplementation, or medication — helping you stay active and independent.
