Fig 1. Images of a 44-year-old male volunteer. A, Multishot diffusion-weighted image with MPG applied in the SI direction shows the left ophthalmic nerve not only in the cistern (arrow) but also in the midbrain (arrowhead). The bright signals in the center of the midbrain are considered to be the decussation of the superior cerebellar peduncle running in the lateral direction. B, STIR image shows the cisternal portion of the left ophthalmic nerve (arrow); however, the nerve is not identified in the midbrain.
