Bone Density Scan
The participant lies down on a padded platform while a mechanical arm passes over your body. The amount of radiation the participant is exposed to is very low, much less than the amount emitted during a chest X-ray. The test usually takes about 10-15 minutes and gathers information on the amount of bone and muscle in your body in addition to bone measures in your hip and spine.

CT Scan
A CT scan is a more detailed way to see the structure (or inner workings and connections) of the bones. The participant sits or lies back with an arm or leg resting on a support inside the scanner. The machine will scan more than one place, such as your ankle, lower leg, middle forearm and wrist.
