A DEXA scan is a dual-energy X-ray method that measures your bone mineral density and bone loss. It’s used to calculate osteoporosis and fracture risk. What is a DEXA scan?
Bone density tests are easy, fast and painless. Virtually no preparation is needed. Be sure to tell your doctor beforehand if you've recently had a barium exam or had contrast material injected for a CT scan or nuclear medicine test.
A DXA scan (bone density test) is a quick, painless way to check your bone health. It’s similar to a regular X-ray, but measures the strength and mineral content of your bones instead of just taking pictures of them. Providers use DXA scans to screen you for osteoporosis, osteopenia and other conditions that can silently weaken your bones.
So, your doctor recommended a bone density test? Don’t worry. Unlike other preventative tests, this one is quick, easy, and painless!
I will explain what a DEXA scan is, walk you through how to prepare for the examination, describe what will likely happen during the examination, identify any risks, and provide insight into how to interpret the results of the DEXA scan.
A bone mineral density test examines segments of your bone through X-rays to detect osteoporosis. The test is quick and painless, and it gives you a snapshot of how strong they are.
A bone density scan is a diagnostic radiology exam used to measure bone mineral content and mass. This is usually performed with an X-ray, called a DEXA scan, or with a computed tomography (CT) scan of the bones .
