Ultra-High-Field Magnetic Resonance Imaging of the Human Inner Ear at 11.7 Tesla.

ABSTRACT:

Objective

To evaluate the ability of ultra-high-field magnetic resonance imaging (UHF-MRI) at 11.7 T to visualize membranous structures of the human inner ear.

Specimens

Three temporal bones were extracted from cadaveric human heads for use with small-bore UHF-MRI.

Intervention

Ex vivo cadaveric temporal bone specimens were imaged using an 11.7 T magnetic resonance imaging (MRI) scanner via T1- and T2-weighted-imaging with and without contrast.

Main outcome measure

Qualitative visualization of membranous components of the inner ear compared with reports of UHF-MRI at lower field strengths.

Results

The membranous anatomy of the inner ear was superbly visualized at 11.7 T. In the cochlea, Reissner's membrane, the scala media, and the basilar membrane were
