WebTwo kinds of NMR signal are generally used in MRI: free induction decay (FID) and spin echo. FID is elicited by a single RF pulse (e.g., 90 degrees) (Figure 3-1 ). The FID decays with the time constant T2*. The decay of the NMR signal can be recovered by applying a second RF pulse, called a 180-degree pulse. WebOne problem associated with measuring a free induction decay (FID) is that, due to the T2∗ relaxation, its amplitude rapidly decreases.
