| Animal | Cochlea | Utriculus | Lateral Canal | Anterior Canal | Posterior Canal | IAMb | Artifacts |
|---|---|---|---|---|---|---|---|
| A | 4 | 4 | 1 | 2 | 4 | 3 | Moderate |
| B | 4 | 4 | 1 | 1 | 4 | 4 | Unremarkable |
| C | 5 | 5 | 2 | 1 | 4 | 5 | Unremarkable |
| D | 3 | 3 | 1 | 1 | 1 | 3 | Severe |
| E | 4 | 4 | 1 | 1 | 3 | 3 | Moderate |
| F | 5 | 5 | 1 | 1 | 4 | 4 | Moderate |
| Ref. | 5 | 5 | 3 | 3 | 5 | 3 | Unremarkable |
Note:—Ref. indicates reference; 1, not visible; 2, visible, not diagnostic; 3, moderate but sufficient; 4, good quality; 5, excellent quality.
↵a First, the depictability of the lateral and anterior semicircular canals is also moderate in the reference examination and, therefore, likely to be a normal anatomic finding at that stage of development. Second, severe artifacts only occurred in animal D due to breech presentation of the fetus.
b Scoring includes visibility of cranial nerves VII and VIII.
