My brother has had a spinal cord stimulator for about six years now. His doctor at the time told him that it was not safe for him to have an MRI, x-ray, ultrasound or any other exam except a CAT scan. He's recently started having problems with the unit and I want him to be checked out. He was scheduled for an x-ray but cancelled it because he is concerned it could damage his unit. Does having an x-ray pose a risk for someone with this type of device? I found one webpage (http://www.spineuniversity.com/spinal_cord_stimulators
) that concurs with his assertion, but it doesn't say why and I haven't found any other websites that warn against having x-rays. Any information you can give me would be very helpful. Thank you in advance.
