Abstract

A method for determining if an implantable medical device (IMD) in a patient is magnetic resonance conditional. Embodiments include a Home Monitoring Service Center (HMSC) that indicates if the IMD is MR conditional and what those conditions are. The IMD includes memory with flags, enabling a physician to set a flag to “MR conditional” if the IMD is MR conditional, if there are no abandoned leads in the patient, and if there are no other hardware in the patient that are not MR conditionally approved. In embodiments, the flags indicate safe for 1.5 T, 3.0 T, 1.5 & 3.0 T, up to 2 W/Kg, up to 4 W/Kg, with/without exclusion zone, and date flags are set. During home monitoring, the HMSC reads out a status of the MR conditional flags and the date last confirmed. If the patient needs an MRI scan, physician queries HMSC to determine MR conditional status.
