Bone Densitometry is a low-dose x-ray that checks for mineral loss and bone thinning and is the leading diagnostic tool for Osteoporosis. The area x-rayed is usually the spine or hip but may also be performed on the wrist. A bone density exam is a simple, painless and non-invasive exam which takes approximately 10 minutes. After an initial exam is done, subsequent tests are useful in monitoring your rate of bone loss.
Preparing for a DEXA
You should not have a barium study, radioisotope injection, oral or intravenous contrast material from a CT scan or MRI within seven days of a DEXA scan. Avoid taking calcium supplements for at least 24 hours prior to your appointment. Wear loose, comfortable clothing without zippers.
