Hi Ken,
I can confirm that Mirena and Paragard (the two most common IUD types in
use in the US) are safe around NMRs and MRIs.

The question has come up recently in our facility if there is any concern for
users of NMRs with IUD's. We have one older Oxford magnet that is the only
one with a significant fringe field.
My limited 'research' indicates that most IUDs are safe for MRIs with the
exception of stainless-steel IUD's.
Does anyone have any further information specific to NMR use?
Thank you.
