Odd MRI sensation

I had my second breast MRI yesterday, a year after my first one. I had an odd sensation with this one - I could feel my left breast having some kind of painless twitching at times, like a small muscle spasm. At this point, I have 5 titanium markers in the left breast, and I'm small breasted. Could there be a chance that the metallic clips were interacting with the machine at all? Maybe it was my peripheral nerves being stimulated.

No results back to report.
