Figure 2. MRI and DTI images showing the facial nerve (cranial nerve VII, CN VII) and the vestibular-cochlear nerve (cranial nerve VIII, CN VIII) at the cerebellopontine angle. A unilateral vestibular schwannoma (VS) grade I is visualized on standard (A) and high-resolution T2 sequences (B). (C) A tensor map is generated in multiple axes and high-resolution diffusion tensor data is generated. Tensors were suppressed below a predetermined threshold. (D) The high-resolution images were then processed to generate tractography images of CN VII and CN VIII. (E) The improved resolution between these two cranial nerves is seen in the panel.
