The Spin-echo Pulse Sequence

The pulse sequence in MRI describes the series of RF pulses, gradient manipulations, and signal measurements that permit collection of sufficient data to form an image or set of images.1 The pulse sequence diagram is like an orchestral score. Time proceeds linearly from left to right. Instead of orchestrating different instruments, the MRI pulse sequence diagram (Figure 4.1) describes the different operations that must occur to generate and collect image data: RF pulses, gradient manipulations, and signal measurement.
