A DEXA scan at Touchstone Medical Imaging requires minimal preparation. You can eat and drink normally leading up to the test, but if you use calcium supplements, you shouldn’t take them for 24 hours before the scan. Dress in loose, comfortable clothes. Avoid belts or clothing that have zippers or metal buttons. Leave jewelry at home. If you wear glasses, you may need to remove them during the scan. Tell your doctor and the imaging team ahead of time if you are pregnant or have recently had an imaging scan involving barium or contrast material. In these instances, your DEXA scan may be delayed or administered with extra safety precautions.
