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 (far less radiation than a standard X-ray)
  • You remain fully clothed (but without metal objects, buttons, zips etc.)

This technology is particularly clever because:

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