Figure 6a. Cranial nerve MR imaging with temporal dual phased-array coils. (a) Transverse fast SE T2-weighted image (4,000/126 [repetition time msec/echo time msec], reformatted) demonstrates both trigeminal nerves crossing the prepontine cistern (black arrowheads) and trifurcating within the Meckel cavity (trigeminal cave) (white arrowheads). Spatial resolution is 0.2 mm3/voxel. (b) Coronal T1-weighted SPGR image (23/4; flip angle, 45°) demonstrates the right oculomotor nerve (arrow) passing beneath the right posterior cerebral artery (arrowheads). Spatial resolution is 0.7 mm3/voxel.
