Figure 2

Head-average SAR for different sequences simulated. Left: Multiple spin echo (ME) with TR=200ms and TE=11ms; the duration of 90° and 180° pulse are 3ms and 1.5ms, respectively. Right: Gradient echo (GE) at TR=200ms and pulse duration of 1ms. Also simulated (but not shown in this figure) was a continuous-wave (CW) excitation. For all sequences, the time-average SAR over the head is 3W/kg.
