Abstract
In vitro experiments were performed to determine the compatibility of a cochlear implant at 0.2- and 1.5-T magnetic resonance (MR) imaging. Except for the torque at 1.5 T, all electromagnetic interferences remained within acceptable limits. MR imaging should be performed only if there is a strong medical indication, by following appropriate safety procedures. MR imaging at 0.2 T should be safe; at 1.5 T, however, the relative risks will have to be assessed.
