Reproducibility of tractography and reliability of the shape descriptors. (a) Three subjects with the best performing test-retest results are selected for their small differences in test-retest volume. The tractography from test and retest scans is of high similarity, while the unique structural characteristics of each subject are preserved. (b) Three subjects with the worst performing test-retest results are selected as a comparison. Even at its worst, the fiber tracking still achieves decent consistency between test-retest scans and preserves the structural characteristics of each subject. (C) The test-retest reliability of the shape descriptors is quantified by intraclass correlation (ICC). The majority of the shape descriptors show moderate (>0.5) to good (>0.75) reliability. The median ICC values for all descriptors are greater than 0.5, while poor reliability (<0.5) still presents in around 6% of the application scenarios.
