Detection of Postoperative Residual Cholesteatoma With Non-Echo-Planar Diffusion-Weighted Magnetic Resonance Imaging

Abstract

Except for motion artifact-degraded examinations, non-EPI-DW MRI is able to detect even very small residual cholesteatoma after first-stage surgery by showing a high-signal intensity lesion. It has the capability of selecting patients for second-look surgery, avoiding unnecessary second-look surgery.
