Magnet Frequency Drifting May Cause Poor Fat Sat Scans due to Z2 Autoshim Disabled in MRconfig.cfg.
Symptom
Magnet Frequency Drifting May Cause Poor Fat Sat Scans. On HFO (OpenSpeed) systems, when scanning with Fat Sat for longer than seven minutes, the center frequency drifts causing two long acquisition scans (11minutes) to lose the fat sat on every other slice. When scanning Fat Sat longer than ~7 mins, center frequency can drift causing poor saturation.
