Table 2.
Visibility of major white matter structures in utero across the repeated DTI scans. A structure was classified “not visible”, if it cannot be seen on any of the repeated scans, “not reproducible” if it was only seen on one scan, “moderately reproducible” if it was visible on two of the three scans, “highly reproducible” if it was visible on all three scans. Frequency means the average detectability of the tract in an individual across the repeated scans (0–100%).
| Name of structure | Not visible, % (number of subjects) | Not reproducible, % (number of subjects) | Moderately reproducible, % (number of subjects) | Highly reproducible, % (number of subjects) | Frequency (%, mean ± SD, min-max) |
|---|---|---|---|---|---|
| Corpus callosum, genu | 16% (4/25) | 8% (2/25) | 28% (7/25) | 48% (12/25) | 69.3 ± 37.1% |
| Corpus callosum, splenium | 20% (5/25) | 16% (4/25) | 28% (7/25) | 36% (9/25) | 60 ± 38.5% |
| Internal capsule, posterior limb | 6.67% (2/30) | 33.3% (10/30) | 20% (6/30) | 40% (12/30) | 64.4 ± 33.8% |
| Brainstem fibers | 30% (9/30) | 30% (9/30) | 26.7% (8/30) | 13.3% (4/30) | 41.1 ± 34.7% |
| Temporal and occipital association fibers | 20% (6/30) | 20% (6/30) | 16.7% (5/30) | 43.3% (13/30) | 61.1 ± 40.2% |
| Probst's bundles | 0% (0/5) | 20% (1/5) | 20% (1/5) | 60% (3/5) | 66.7 ± 33.3% |
