Faster and Stronger Gradients: Part 2

33 Faster and Stronger Gradients: Part 2

This case illustrates the effect of faster and stronger gradient systems on fast spin echo techniques (Fig. 33.1). The benefits applicable for sequences with a single echo, as explained in Case 32, also contribute to an improvement in multiecho techniques such as fast spin echo. The most important factor for multiecho techniques is “faster” gradients, that is, minimizing the time for the gradients to reach their nominal value. Once the gradients achieve their nominal value, excitation or refocusing pulses can be applied or data sampling can be initiated.
