LEARN MORE ABOUT DEXA

The name “DEXA” stands for “Dual-Energy X-ray Absorptiometry,” which directly describes this two-beam technology. A DEXA scan works by using two distinct low-dose X-ray beams with different energy levels that pass through your body.

How DEXA Works

Two X-ray beams with different energy levels are aimed at your bones.
Different types of tissue (bone, muscle, fat) absorb these X-rays at different rates.
The absorption difference between the two X-ray energies helps distinguish bone from soft tissue.
Advanced software analyses these differences to create detailed images and measurements.

During the Scan:

You lie still on a padded table
A scanner arm passes over your body
The process takes about 10-20 minutes
It's painless, non-invasive and 100% safe (less radiation than a standard X-ray)
You remain fully clothed (but without metal objects)

This technology is particularly clever because:

The dual-energy approach allows it to separate bone from soft tissue
It can distinguish between fat and lean tissue
It provides highly accurate measurements with very low radiation exposure
It can create detailed regional analysis of different body parts
