Virtual endoscopy (VE) of the labyrinth was performed using three-dimension
al (3D)-fast asymmetric spin-echo MR Imaging. The spatial resolution requir
ements and the usefulness of zero-fill interpolation (ZIP) were evaluated,
and VE was used to examine three patients. The (0.6-mm) voxel data with ZIP
satisfies the minimum requirements for VE for evaluation of the complex 3D
anatomy and pathology of the labyrinth. (C) 2001 Wiley-Liss, Inc.
