Temperature measurements were made in a phantom at the
tip of a deep brain stimulator lead. The DBS components
were arranged in various configurations and scanned at
high and low SAR with body coil transmit. The
temperature increase for the lead only and lead +
insertion stylet was in the range of 0.5 - 3.2C at high
SAR and < 0.1C at low SAR. The full DBS system resulted
in heating of 14.4C at high SAR and 0.25C at low SAR.
There is increasing interest in evaluating heating of
leads with body coil RF transmit, which is
contraindicated.
