Coronal oblique secondary reconstructions of the same patient with cochlear implants. These images illustrate the variable image quality obtained with identical 3-mm section thickness, window width (3681), contrast (1246), and kernel type (HU). Note the blurring and poor visualization of the electrode contacts with the very smooth (A) setting. A sharp (D) parameter produces optimal images with well-defined osseous structures and individual electrode contacts. (A) Very smooth, (B) normal, (C) auto, (D) sharp.
