It all depends on the jewelry, where it is located, and what part of your body is being scanned. If we sold you the jewelry, we can tell you exactly what metal it is made of so that your technician can determine its safety. We can also provide you with a card that states what material your jewelry is made of. Much of the jewelry we sell is made from implantation certified materials that are known to be safe for all medical procedures. If your jewelry is of a safe material, it will be up to your technician to determine if your jewelry will interfere with the picture they are taking.
