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 (https://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.
