Abstract

Steady state free precession (SSFP) imaging with unbalanced gradients (e.g. FISP, PSIF, DESS) causes aliasing in k-space which is often overlooked, or at best, minimised with large spoilers. Here we exploit this phenomenon and use the aliased signals to increase the SNR-efficiency of SSFP imaging.
