The 3D-EPI showed a trend of lower sensitivity and higher specificity compared to the SMS-EPI sequence, these differences were however not statistically significant neither for AR(1) (paired t-test with 9 degrees of freedom, p = 0.58 and t = 0.57 for the sensitivity; p = 0.44 and t = 0.81 for the specificity) nor for FAST (p = 0.91 and t = 0.12 for the sensitivity; p = 0.68 and t = 0.43 for the specificity).
