Numbers are reported as mean ± standard deviation.
Lower values represent better image quality (reduced artifact conspicuity).
a
Indicates no statistical difference between magnitude and PSIR images.
b
Indicates statistical significance (P < 0.05) compared with all other methods.
Pre-Sat, saturation Pre-Pulse; Pre-Sat-plus-dummy, saturation pre-pulse with dummy acquisition; PSIR, phase-sensitive inversion recovery; SPPRESS, saturation post-pulse readout to eliminate spurious signal.
