VERIFICATION THAT A PATIENT WITH AN IMPLANTABLE MEDICAL SYSTEM CAN UNDERGO A MAGNETIC RESONANCE IMAGING SCAN
First Claim
1. A method of checking whether a magnetic resonance (MRI) image scan can be performed for a patient who has an implantable medical system, the method comprising:
- verifying by an external device that an implantable medical device of the implantable medical system is of a type that is acceptable for the MRI scan;
verifying by the external device that an implantable medical lead of the implantable medical system is of a type that is acceptable for the MRI scan; and
providing by the external device an indication of whether the implantable medical system is acceptable for the MRI scan based on the verifying of the implantable medical device and the implantable medical lead.

Abstract
Verification that an implantable medical system within a patient is MRI safe is provided. Several verifications may be performed such as verifying that the device and leads are of an MRI safe type, that the leads have adequate electrical integrity, that the device has entered an MRI safe mode, that the lead routing and device placement are MRI safe, and that the MRI settings of the MRI machine are safe for the implantable medical system. The result of these verifications may lead to a conclusion that the implantable medical system of interest is or is not MRI safe for a given MRI scan. An indication of this result may be output such as via a display so that an MRI technician can have some assurance as to whether to conduct the MRI scan.
