Fig 3. Axial 3D-bFFE images of the lower cranial nerves from the level of the cochlear aqueduct to the level of the lower margin of the JF on the left side. A and B, The white arrows indicate the recess for the cochlear aqueduct. C–E, Just below the level of the cochlear aqueduct, the glossopharyngeal nerve (small black arrows in C–E) is visualized in the recess for the glossopharyngeal nerve (white dotted arrow in C and D). Just inferior to the glossopharyngeal nerve, there is a dural ring seen as slightly dark signal intensity at the apex of the JF (white crossed arrow in E). F and G, Just below the level of the dural ring, the recess for the CN X/XI complex (white arrowhead) and the vagus nerve (black arrowhead) is visualized. H, The spinal accessory nerve (black arrow) is visualized in the recess for the CN X/XI complex (white arrowhead) at the level of the lower end of the JF.
