MR conditionality of two MR Conditional DBS ipsilateral implants with separate IPGs

Previous investigations of RF-induced heating of multiple implants (active as well as passive) have shown that heating of an implant can be impacted by the presence of a separate neighboring implant. This work assessed to which extend this phenomenon is present for the limited scope of two separate MR Conditional ipsilateral DBS implants, one on one side of the body, and another on the other side. Both, RF-induced heating and voltage injection level into the IPG were assessed. A variety of DBS lead configurations, and clinically relevant distances in-between the two separate implants, were thoroughly assessed for a data-driven conclusion.
