MRI has become so common-place that many doctors forget that not everyone is a candidate. I had a very early MRI and, at the time, they almost excluded me because I was a truck mechanic/welder and MIGHT have had metal slivers somewhere. Those slivers could move or pull out during the scan, causing damage.

If someone has said that newer stimulators use completely non-ferrous materials (won't be pulled by a magnet) and that is why it is OK, you would need to verify that with the manufacturer. But I believe that the MRI Tech would probably refuse to do it simply because of the liability risks.
