Discover the Differences Between DEXA and REMS Scans for Bone Health

Keeping your bones healthy is vital, especially as you get older or face risks like osteoporosis. Two common tests for checking bone health are the DEXA scan and the REMS scan. While they share the same goal, they use different technologies. Knowing how they work can help you choose the right one.

Here’s an easy-to-follow guide to understanding DEXA and REMS scans, their key differences, and when to choose one over the other.

What Are DEXA and REMS Scans?

DEXA Scan

• How it works: Uses low-dose X-rays to measure calcium and other minerals in your bones.

• What it does: Provides a Bone Mineral Density (BMD) score to assess bone strength and risk of fractures.

• Common focus areas: Spine, hips, and sometimes the wrist.

• Reputation: Known as the “gold standard” for diagnosing osteoporosis due to its accuracy.

REMS Scan

• How it works: Uses ultrasound waves instead of X-rays to analyze your bone’s structure and density.

• What it does: Measures echo patterns from sound waves passing through your bones.

• Common focus areas: Lumbar spine and femoral neck (hip area).

• Why it’s unique: Radiation-free, making it safer for repeated scans.

Key Differences Between DEXA and REMS Scans

Here’s a quick side-by-side comparison:

Feature	DEXA Scan	REMS Scan
Technology	Low-dose X-rays	Ultrasound waves
Radiation	Minimal exposure	No exposure
Availability	Widely used	Newer, less available
Portability	Requires large machines	Compact and portable
Insurance Coverage	Often covered	Coverage varies

Pros and Cons of Each Scan

DEXA Scan

Pros:

• Highly accurate and well-researched.

• Results can be used across multiple clinics.

• Helps calculate FRAX (Fracture Risk Assessment Tool).

Cons:

• Exposes you to a small amount of radiation.

• Requires a visit to a hospital or imaging center.

• Not ideal for frequent scans.

REMS Scan

Pros:

• Completely radiation-free.

• Portable and great for remote areas or quick access.

• Promising accuracy similar to DEXA.

Cons:

• Limited availability in many places.

• May not yet be covered by all insurance.

• Research on long-term efficacy is still ongoing.

When Should You Choose DEXA or REMS?

Go for a DEXA Scan if:

• You need a trusted, gold-standard test to confirm osteoporosis.

• Your doctor recommends it based on risk factors like age or previous fractures.

• You prefer a widely available test covered by most insurance plans.

Consider a REMS Scan if:

• You want to avoid any radiation (great for children, pregnant women, or frequent monitoring).

• You're in an area with limited access to traditional imaging centers.

• You prefer a portable and on-the-go diagnostic tool (e.g., rural clinics or health fairs).

Always talk to your healthcare provider to decide which test fits your needs best. Cost, insurance coverage, and medical advice should guide your decision.
