Risk of injury, death or destruction of the animal/sample under investigation
carrying implants.
Ferromagnetic or electrically-conductive materials inside the sample or object under
investigation (i.e. aneurysm-clips, prostheses, shrapnel, metal splinters, needles etc.)
may dislocate due to the extreme forces exerted by the magnetic field. This may
result in severe internal injuries or destruction of the sample.
Animals bearing ferromagnetic implants might be attracted so strongly by the
magnetic field that they eventually cannot be removed from the magnet again.
No animal/sample carrying ferromagnetic implants may be brought into the MRI
magnet.
Risk of damage to magnetic data media, watches etc.
The magnetic field may
erase magnetic data media (e.g. magnetic disks, magnetic tapes, diskettes,
credit cards)
destroy mechanically sensitive components (e.g. watches, cameras)
Do not bring any of these items into the MRI magnet.
