Objective: This study aimed to quantify the demagnetization of the magnet of a new Cochlear Implant with removable magnet in a 1.5 T and a 3.0 T MRI scanner in vitro.
Study design: Experimental cadaver head model. Subjects and Methods: Ten implant magnets were examined through a routine protocol in a 1.5 T and 3.0 T MRI scanners. Magnetization prior to and after the experiment was measured.
Results: No statistically relevant change in the magnetization of the magnets was observed for in the surrounding of the MRI scanner or the isocente... view more»
