Synopsis

This study evaluates the feasibility of different approaches for the visualization of endolymphatic content in inner ear structures on 1.5T MR systems without the need of contrast injection. The results show that using an optimized high-resolution 3D T2w sequence combined with DLR-based denoising tools it is possible to visualize the utricle and saccule structures on healthy volunteers. The next step will be testing this technique on patients with endolymphatic hydrops.
