For each combination of reconstruction repetition or type of head-coil with streamline selection variant, numbers in cells refer to the percentage of intra-class correlation coefficient (ICC) type ICC(2,1) values falling within each of the following three categories: ICC(2,1) <.60, corresponding to low reproducibility; ICC(2,1) between .60 and .69, corresponding to marginal reproducibility; ICC(2,1) ≥.70, corresponding to adequate reproducibility or higher. 1 Rep, 1 reconstruction repetition; 10 Rep, 10 reconstruction repetitions; 12ch, 12-channel head-coil; 32ch, 32-channel head-coil; end_nofuz, endpoint_nofuzzy; end_fuz, endpoint_fuzzy; vis_nofuz, visiting_nofuzzy; and vis_fuz, visiting_fuzzy streamline selection.
