- Fig 1.
Coronal view (thin-section MIP; section thickness, 0.5 mm) shows the normally developed cochlea (open arrows) and the tympanic cavity (closed arrows), which are both (normal findings in utero) fluid-filled in the reference examination (A, 3D CISS, stillborn lamb) as well as in vivo (B, 3D True FISP).
- Fig 2.
This set of axial views of the reference examination (A, 3D CISS, stillborn lamb) and in vivo (B, 3D True FISP; both thin-section MIPs; section thickness, 0.7 mm) displays the IAM with the seventh and eighth cranial nerve (arrows) and a cross-section through the normally developed cochlear modiolus, which is also well-depicted.
- Fig 3.
The axial views of the reference examination (A, 3D CISS, stillborn lamb) and in vivo (B, 3D True FISP; both thin-section MIPs; section thickness, 2.0 mm) display the utriculus (open arrows) and the medial section of the posterior semicircular canal (closed arrows). The utricular ostium of the lateral semicircular canal can be seen as well in both images.

↵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.
