Here we tested the boundaries of the speed and precision of phase MREPT in brain using balanced FFE. Baseline maps with conductivity variance of < 5% could be safely accelerated with compressed SENSE 6 without sacrifice of precision, and scans acquired as quickly as 1.89 s. Precision could be further improved by whole head B1 mapping. MREPT mapping should be conducted task free for best results.
