Another helpful reply about stents and othe implantable objects:
I just read your summary of stents in the magnetic environment.
The relative safety of stents is highly variable between types and models.
Heating issues (and increased release of medication) are largely a product of RF energies. Torque and translation are, of course, a product of the static magnetic field.
Due to the variety of materials and structures, some stents are safe immediately following implementation, while others have lifetime hazards in the MRI / nMR environment.
I recommend that people verify the safety of their (their researchers') specific medical devices against the list (

https://exchange.uconn.edu/exchweb/bin/redir.asp?URL=http://mrisafety.com/list.asp> ) or against the device / implant manufacturer's most current safety guidance. This should be a pre-requisite for any medical device patient approaching the magnet.
I hope that this is helpful to you and others on the AMMRL list.
Respectfully,
Tobias Gilk
