MRI-compatible implants

[I posted this a while ago on sci.med.radiology, but few visit that
board, so let it be flown here.]

A company devises a specialized coating for pacemakers,
bone pins and screws, stents, catheters, neurostimulators, electrodes,
etc., that

1, completely eliminates "blooming" around the implant on the
MRI scan image, and


2, eliminates or drastically reduces heating in metallic implants
caused by induction from the MRI's magnetic field.


QUESTION: So what? Is it worth anything?

In other words: Are current work-arounds to the above-mentioned
problems cost-effective enough and efficacious enough to preclude the
bother of introducing (and adjusting to) new coatings?
