<p>If you have any implants of any material or a Pacemaker, the scan can go ahead as normal. Metal implants will show up as dense bone on your NuMi DEXA report but they will not affect the fat and lean mass data. There is no risk to the operation of your Pacemaker. There is no risk to the structure of operation of your implant. &nbsp;The DEXA is a very low dose X-ray, and X-rays either pass through objects or they do not.</p>
