↵a Wilcoxon matched-pairs signed-rank test was used to compare reader image-quality ratings of sequences.
↵b SSFSE was scored significantly higher than both half- and full-Fourier vrfSSFSE for Motion Artifact (P < .001).
↵c Both vrfSSFSE sequences were rated significantly higher than SSFSE for Sharpness: Brain-Fluid (P < .001).
↵d Both vrfSSFSE sequences were rated significantly higher than SSFSE for Sharpness: gray-white contrast (P < .001).
