The IPG’s contribution to the limitation of RF currents is relatively
small (1.03 to 8.04%, mean 2.72%). A
maximum difference of 4.85% was found for a hybrid system, which is probably
negligible when considering lead impedance variability.

impedance against the total lead/IPG impedance to 63.87 MHz RF currents at the
lead’s Tip electrode. Lead/IPG pairs are
MR-conditional labeled for whole-body MRI at 1.5T.

Lead impedance incorporates the effect of the implantable device’s
enclosure in gel slurry. Lead/IPG pairs are MR-conditional labeled for
whole-body MRI at 1.5T.
