Research Abstract

With increased spatial resolution and reduced susceptibility artifacts, our newly developed high-resolution three-dimensional diffusion-weighted imaging (DWI) method allows for reformation in any arbitrary plane, and improves the accuracy in diagnosing acquired middle ear cholesteatomas compared to convensional DWI.
