While imaging subjects in an MRI scanner, it may sometimes be necessary to de-fibrillate in order to restore sinus rhythm or resuscitate. Normal de-fibrillator equipment is incompatible with the scanner's magnetic field. Presented is a procedure for de-fibrillating inside the MRI environment. With this procedure, the defibrillator unit was located outside the MRI environment, with select non-ferrous equipment inside and on the subject. This procedure was employed on four separate occasions with an animal subject on the scanner table, and was found to be successful. No problems or safety concerns were observed.
