Distortion Scoring by Observer

Observer rFOV Improvement
Significance		 CONV - rFOV Difference
(0–4 Scale) (Average ± SD)
1 p<0.0063 0.56±0.68
2 p<0.0117 0.48±0.61
3 p<0.0010 0.52±0.65

Wilcoxon Signed-Rank Tests for difference in distortion scoring among patients show a significant decrease in observed distortion in ADC maps created from the reduced-Field-of-View (rFOV) sequence compared to the conventional (CONV) sequence for each observer (n=50). The average decrease in distortion score is similar for all observers, p=0.99, Kruskal-Wallis Rank Sum Test, SD = standard deviation.
