A DXA scan produces an extremely low amount of  radiation (1-4 uSv).  To put that in perspective, the average person receives about 8 uSv of radiation by merely walking around on Earth.  In fact, 3-4 DXA Body Composition Scans scans within one year are safe.  A round trip cross-country flight exposes you to much more radiation (40uSv).

In short, no.  The DXA Bone Density scan is a scan that zeros in on certain parts of your body, usually your hip, spine and/or forearm to determine how dense your bone is and your fracture risk.  This scan can assist in diagnosing osteoporosis/osteopenia.  

The DXA Body Composition Scan scans your entire body and provides detailed information about specific amounts of bone, fat and lean tissue in each region of the body.

The scan itself takes six minutes.  You must be able to lie flat on a cushioned table (without any pillows or bolsters) for that time in order to get accurate results.  To allow for screening, dressing and consult time, plan on being at IMPACT for approximately 30-45 minutes. 

You cannot have any metal on your clothing for the DXA scan (metal internal implants are fine).  This includes zippers, bra clips or underwire, buttons, clasps or metal eyelets (for draw-string pants or sweatshirts).  This also includes jewelry and/or money clips – best to leave jewelry and any metal valuables at home.  Gowns are available as needed.

Fasting is not required, but be sure you are hydrated.  If you are looking for extremely accurate results, you may want to fast from solid foods for at least one hour prior to the scan and plan to do any repeat DXA scans at the same time of day as your initial scan.
