Figure 11a. High-spatial-resolution MR imaging of the internal auditory canal by using dual single-circular-element coils (temporomandibular joint coils). (a) Transverse T2-weighted fast SE 3D Fourier transform image (4,000/126) demonstrates a vestibular schwannoma (arrow) in the left internal auditory canal. Spatial resolution is 0.4 mm3/voxel. (b) Oblique sagittal T2-weighted fast SE 3D Fourier transform image (4,000/110) in another patient demonstrates nerves within the internal auditory canal: superior vestibular (small arrowhead), inferior vestibular (large arrowhead), facial (curved arrow), and cochlear (straight arrow) nerves. Spatial resolution is 0.2 mm3/voxel.
