Will I need to do anything to prepare for these tests?
Tell your health care provider if you have a pacemaker or cardiac defibrillator. Special steps will need to be taken before the test if you have one of these devices.
Wear loose, comfortable clothing that allows easy access to the test area or can be easily removed if you need to change into a hospital gown.
Make sure your skin is clean. Don't use lotions, creams, or perfumes for a day or two before the test.
