WebGradient echo (GRE) sequences begin as a regularly spaced series of radiofrequency (RF)-pulses repeated at time interval TR. These RF-pulses are often chosen to have flip angles (α) less than 90°, but can have any value. A train of evenly spaced RF pulses produce "FID-like" and "Echo-like" signals. Each RF-pulse generates a free induction ... WebSusceptibility Weighted Imaging.
