DEXA scans are usually outpatient procedures. There aren't any special preparations needed, except to stop taking any calcium supplements for 24 hours before the test. Wear comfortable clothing. Depending on the body area being scanned, you may have to take off any clothes with metal fasteners, zippers, or hooks.

Along, what is a DEXA scan and how long does it take?

An X-ray detector inside the scanning arm measures the amount of X-rays that have passed through your body. This information will be used to produce an image of the scanned area. The scan usually takes 10 to 20 minutes. You'll be able to go home after you have had it done.

Still and all, what is a normal DEXA scan score? DXA Scan Results T-score of -1.0 or above = normal bone density. T-score between -1.0 and -2.5 = low bone density, or osteopenia. T-score of -2.5 or lower = osteoporosis.

For that reason, what are the benefits of a DEXA scan?

The primary reason why doctors ask to get a DEXA scan done is to find out whether or not you are suffering from bone loss(osteoporosis). It will also prevent disability and fractures. With age, the bones in your body become more brittle and weaker. They end up losing the calcium content in them.

What should you not do before a DEXA scan?

You should not take calcium supplements for at least 24 hours before your exam. You should wear loose, comfortable clothing, avoiding garments that have zippers, belts or buttons made of metal. Objects such as keys or wallets that would be in the area being scanned should be removed.
