What Is a DEXA Scan? A Complete Guide for Patients

At Independent Physicians Medical Center (IPMC) in Northeast Philadelphia, we offer advanced DEXA bone density testing in a comfortable outpatient setting—making it easy to monitor and protect your bone health.

What Is a DEXA Scan?

DEXA stands for Dual-Energy X-ray Absorptiometry. It uses a very low dose of X-ray technology to measure the mineral content of your bones—most commonly at the hip and spine.

This test helps doctors:

• Diagnose osteoporosis
• Detect osteopenia (low bone mass)
• Estimate fracture risk
• Monitor response to treatment

Because osteoporosis often develops without symptoms, a DEXA scan is one of the most important tools for early detection.

Who Should Get a DEXA Scan?

Your doctor may recommend a bone density test if you:

• Are a woman age 65 or older
• Are a man age 70 or older
• Have experienced a low-impact fracture
• Take long-term steroid medications
• Have early menopause
• Have a family history of osteoporosis
• Have certain medical conditions affecting bone health

Younger adults with risk factors may also benefit from testing.

If you live in Northeast Philadelphia, Bustleton, Rhawnhurst, or surrounding communities, IPMC provides convenient access to advanced bone density imaging close to home.

What Happens During the Test?

A DEXA scan is simple and painless.

Here’s what to expect:

• You’ll lie comfortably on a padded exam table.
• A scanning arm passes slowly over your body.
• The test usually focuses on your hip and lower spine.
• The entire procedure takes about 10–20 minutes.

There are no injections, no enclosed machines, and no downtime. You can return to normal activities immediately after your appointment.

How to Prepare for a DEXA Scan

Preparation is minimal. You may be advised to:

• Avoid calcium supplements for 24 hours before the test
• Wear comfortable clothing without metal zippers or buttons

Be sure to inform your provider if you are pregnant or have recently had a contrast imaging study.

Understanding Your Results

Your DEXA scan results include:

T-Score

Compares your bone density to that of a healthy young adult.

• -1.0 or above: Normal
• Between -1.0 and -2.5: Osteopenia
• -2.5 or lower: Osteoporosis

Z-Score

Compares your bone density to others your age and body size. This is especially useful for younger patients.

Your physician will review your results and determine whether treatment, lifestyle changes, or follow-up monitoring is needed.
