Abstract
We performedin vitro tests of ferromagnetism of platinum microcoils of two manufacturers. In addition, we performedin vitro magnetic resonance imaging (MRI) on these two devices to determine their levels of magnetic susceptibility artifact production. We found that both devices were nonferromagnetic and produced a very low level of artifact during MRI.In vivo MRI of a dog and 2 patients having previous placement of platinum microcoils was performed without coil mignation or significant artifact production. Platinum microcoils are highly MR-compatible.
