Widespread use of phase-cycled bSSFP imaging is hampered by problematic sensitivity to artifacts caused by susceptibility and motion. The geometric solution (GS), which can eliminate susceptibility-related banding and signal modulation, has previously show relative insensitivity to motion. Here, GS-bSSFP is evaluated using a phantom and in humans, imaging the skull base. The GS mitigates motion artifact in both paradigms and is particularly resilient when one of its four phase cycles is corrupted by motion.
