What is a bone density test?
The DEXA (Dual Energy X-ray Absorptiometry) measures your bone mass. This measurement can help your doctor determine whether you need medication to help maintain your bone mass, prevent further bone loss and reduce fracture risk. It measures the hip, spine or the entire body. It works like a chest or dental X-ray. It is quick, safe and easy. You simply lie on a cushioned bed while a scanner arm passes over your body. The entire process takes about 20 minutes. A bone density test is the only way to diagnose osteoporosis and determine your risk of future fracture.
Preparing for your test is easy. You may eat and drink as usual before you visit, but you should not take any calcium supplements for 24 hours before your test.
