DEXA Scan

What is a DEXA Scan?

A DEXA/DXA (Dual-Energy X-ray Absorptiometry) scan, also called a bone density scan, is an imaging test that measures bone density. It is commonly used to diagnose and monitor osteoporosis and other conditions that cause bone loss. The scan uses low-dose X-rays to produce images of the inside of the body, typically focusing on the spine, hip, and sometimes the forearm.

UR Medicine's Approach

DEXA scans are key when it comes to diagnosing and treating osteoporosis—a bone disease in which bones become weak and fragile as they become less dense or their structure changes. UR Medicine is home to some of the nation’s top experts in detecting, treating, and supporting patients with osteoporosis. We will walk you through every step from diagnosis to treatment.

Why is a DEXA Scan Performed?

A DEXA scan is performed to:

Assess bone density and strength
Diagnose osteoporosis or osteopenia (low bone mass)
Monitor the effectiveness of treatment for osteoporosis
Evaluate the risk of fractures

How to Prepare for a DEXA Scan

Preparation for a DEXA scan is minimal. Here are some general guidelines:

Avoid taking calcium supplements for at least 24 hours before the test.
Wear loose, comfortable clothing without metal zippers, belts, or buttons.
Inform your doctor if you have recently had a barium exam or have been injected with a contrast material for a CT scan or radioisotope scan.

What to Expect During a DEXA Scan

During the Scan

You will lie on a padded table. You will need to lie still and may be asked to hold your breath at times.
The scanner will pass over your body, focusing on the areas being examined.
The procedure is quick, usually taking about 10-30 minutes.
It is painless and non-invasive.

After the Scan

There are no special instructions to follow after a DEXA scan. You can resume your normal activities immediately. Your doctor will review the results and discuss them with you, including any necessary follow-up or treatment plans.
