Lisa,
I will second Jan's comment about "no problem" having MRIs with a BAHA implant (the processor isn't worn during the procedure), as well as her recommendation to pursue getting a BAHA -- mine has been a huge help!
I set up my appointment for my one-year follow-up MRI yesterday and sat down with the scheduler for a little chat so that it would be perfectly clear that I need to have the fat suppression option (since I had translab surgery), that I have a titanium implant, that dye contrast is to be used, and that I'll need a CD version to send out west to my surgeons. All of this was on the prescription, but I figure it doesn't hurt to review things verbally as well!
I will also have a similar chat with the technician when I go in for the MRI next week.
Best wishes as your plans develop!
