Preparatory Modules: Saturation Techniques
As mentioned in Chapter 8, the basic pulse sequence requires both an excitation module and a readout module. These pulse sequences can be modified, however, by adding preparatory modules (appetizers in the “pulse sequence menu” of Fig. 8-2). These preparatory modules are essentially different types of saturation techniques. In Chapter 8, we introduced the idea of saturation as a consequence of applying multiple RF pulses. In this chapter, we will apply additional RF pulses to deliberately cause specialized types of saturation in an effort to modulate image contrast in unique ways.
