Bone Density (DXA)

A bone density test — also called densitometry or DXA scan — determines whether you have osteoporosis or are at risk of osteoporosis. Osteoporosis is a disease that causes bones to become more fragile and more likely to break.

Bone Density (DXA)

In the past, osteoporosis could only be detected after you broke a bone. By that time, however, your bones could be quite weak. A bone density test makes it possible to know your risk of breaking bones before the fact.

A bone density test uses X-rays to measure how many grams of calcium and other bone minerals are packed into a segment of bone. A bone density test is a fairly accurate predictor of your risk of fracture.

 

Procedure:  You will be asked to lie flat on your back on a slightly padded table. A mechanical arm-like device passes over your body, this device will not touch you. The bone density of your hip and spine will be measured by the device taking an x-ray. The actual scan time is 5-10 minutes. The results from a bone denisty test shows your fracture risk. The bone density test results are reported in two numbers, T-score and Z-score.
