Final answer:
In MRI, steady state aims to enhance transverse magnetization while spoiled aims to suppress transverse magnetization.
Step-by-step explanation:
In magnetic resonance imaging (MRI), the terms "steady state" and "spoiled" are used to describe different techniques to manipulate the transverse magnetization.
In the steady state technique, the goal is to enhance the transverse magnetization by using radiofrequency pulses and gradients in a way that allows the magnetization to reach an equilibrium state. This technique is commonly used in fast imaging sequences.
In contrast, the spoiled technique aims to suppress the transverse magnetization by applying radiofrequency pulses that quickly dephase the magnetization. This technique can be useful in certain imaging applications where the presence of transverse magnetization causes undesired effects.
