Comparison of field-of-view optimized and constrained undistorted single-shot diffusion-weighted imaging and conventional diffusion-weighted imaging of optic nerve and chiasma at 3T
2018
Purpose
Single-shot echo-planar imaging is the conventional diffusion-weighted imaging (C-DWI) sequence for evaluating orbital disease. However, its utility is restricted in small organs like the chiasma and optic nerve. This study was conducted to investigate the utility of field-of-view optimized and constrained undistorted single-shot diffusion-weighted imaging (FOCUS-DWI) for evaluating the chiasma and optic nerve in acute optic neuritis, making comparisons with C-DWI.
