FIG 2. A, Sagittal T2-weighted MR image demonstrates stenosis at the C4–5, C5–6, and C6–7 levels. The reviewers were inconsistent in determining the level with the most severe stenosis because of multilevel involvement.

B, Axial gradient-echo MR image. On the basis of this image and the sagittal image (A), degree of stenosis judged by the reviewers was inconsistent and ranged from mild to severe in this case.
