WebTrue FISP is the Siemens trade name for a steady-state coherent sequence in which balanced gradients are used along all three axes. "Balanced" means that the net gradient-induced dephasing over a TR interval is zero. Conversely, some of the gradients in FISP and PSIF are unbalanced, allowing recording of separate FID and echo components of the ...
