Thereof, can you eat or drink before a DEXA scan?
On the day of the exam you may eat normally. 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.
One may also ask, how long does a DEXA scan 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.
