Dexa Scan Technology

A dual-energy x-ray absorptiometry, or DEXA scan uses low-dose x-rays to test bone density.

Here’s how it works:

Osteoporosis is a disease of the bones. It happens when you lose too much bone, make too little bone or both. As a result, your bones become weak and may break from a minor fall or, in serious cases, even from simple actions, like sneezing or bumping into furniture, and most commonly occur in the hip, spine and wrist.
