Figure 1.

Examples of interrater disagreement. Subject A was rated as “possible nerve thickening” by rater 1 and as “no nerve thickening” by rater 2. Subjects B and C were rated as “possible nerve thickening” by rater 1 and as “definite nerve thickening” by rater 2. This figure illustrates the difficulties in classifying subtle nerve thickening as either normal or thickening. Each subject represents an example of a maximum intensity projection (MIP) and three‐dimensional short‐tau inversion recovery (STIR) image
