Table 2. Statistics for autocorrelation voxels.
Single-shot EPI | Multi-shot EPI | EPIK | |
---|---|---|---|
rincrease [%] | 27.83 ± 15.33 | 76.93 ± 41.84 | 35.35 ± 20.16 |
rremain [%] | 0.00 ± 0.00 | 15.08 ± 10.62 | 4.65 ± 2.97 |
t-value | 3.76 ± 0.42 | 4.04 ± 0.80 | 3.90 ± 0.66 |
mean ± SD over subjects
The percentages of detected autocorrelation voxels before the AR(1) correction (rincrease) and after the AR(1) correction (rremain) are computed for each imaging method and compared to single-shot EPI (standard method). The t-values for the autocorrelation voxels are also shown. The calculation was performed for all subjects and the mean ± SD over the subjects is listed.
