FIG 2. DBS lead mean temperature elevation as a function of local SAR. Plot shows greatest observed mean temperature elevation for 1 min of data collection, obtained at the time of peak heating during the 10- to 15-minute imaging time interval, versus local SAR value for single and multisection fast spin-echo images. Linear regression (all data points): r = 0.994, P < .001, x variable = 0.88, and y intercept = -0.13.
