| Motion Artifactb | Sharpness: Brain-Fluidc | Sharpness: gray-white contrastd | |
|---|---|---|---|
| SSFSE | 94% | 37% | 50% |
| Half-Fourier vrfSSFSE | 80% | 91% | 90% |
| Full-Fourier vrfSSFSE | 77% | 96% | 94% |
a
Fisher exact tests were used to compare the fraction of scans rated highly, 4 or 5, for each image-quality parameter for SSFSE and vrfSSFSE sequences.
b
There was no statistically significant difference in the fraction of SSFSE scans rated either a 4 (very good) or 5 (excellent) for Motion-Artifact as compared to vrfSSFSE sequences (P > .1).
c
Both vrfSSFSE sequences had a higher fraction of images rated either 4 or 5 as compared to SSFSE for Sharpness: Brain-Fluid (P < .001).
d
Both vrfSSFSE sequences had a higher fraction of images rated either 4 or 5 as compared to SSFSE for Sharpness: Gray-White Contrast (P < .0001).
