Figures
- Fig 1.
Mean differences in scoring of anatomic structures depicted at 3T and 7T. The bars on the right side of the zero line indicate differences in favor of the 7T images. The bars on the left side indicate differences in favor of the 3T images. The structures showing significant differences are marked with an asterisk on the left, and P values are mentioned if significant.
- Fig 2.
Axial cross-section of a right inner ear, rendered at 3T (A) and 7T (B); improved discrimination of the intracochlear structures and compartments is shown. In addition, sharper delineation of the nerves in the internal auditory canal is demonstrated. The single arrow indicates the scala media at the first turn. The double arrows indicate the superior ampullary nerve.
- Fig 3.
Axial cross-section along the course of the facial nerve of a left inner ear, rendered at 3T (A) and 7T (B). A sharp delineation of the neural structures and clear depiction of the intermediate nerve between cranial nerves VII and VIII are demonstrated on the 7T image.
- Fig 4.
In 2 different patients, 7T images showing stripelike-artifacts at the level of the first turn of right (A) and left (B) cochleas, disturbing the quality of the representation and impeding the distinction of the scala vestibuli and tympani.
