Ferromagnetism and magnetic resonance artifacts of platinum embolization microcoils

M W Marshall et al. Cardiovasc Intervent Radiol. 1991 May-Jun.

Abstract

We performed in vitro tests of ferromagnetism of platinum microcoils of two manufacturers. In addition, we performed in 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 migration or significant artifact production. Platinum microcoils are highly MR-compatible.
