I would also provide this information to whomever is going to do the extraction
If you do use a magnet to assist in the extraction, be very careful not to damage your xG3 with it.
although by the sounds of it, you shouldn’t need one for your placement.
I hope whatever the reason for needing an MRI is not too serious and that you recover well from it
to assist in the extraction, be very careful not to damage your xG3 with it.
