Fast spin-echo imaging with high radio-frequency transmitted power was performed while temperature measurements for the grid phantom were recorded by means of fiberoptic thermometry. Temperature variations remained within 1.0°C. MR imaging examination in patients in whom such grid electrodes are implanted is expected to result in clinically insignificant temperature changes in the vicinity of the grid electrode or its leads.Read More
