Table 2. Number of cortical lesions identified after the first reading and re-evaluation.

Number of CL	Rater 1	Rater 2	Consensus lesions (conL)
Number of CL detected in the first reading	230	251	160 (48%)
Number of retrospectively agreed CL	35	38	n.a.
Number of CL detected after re-evaluation	265	289	233 (69%)

Table 2 displays the number of cortical lesions (CL) identified by rater 1 or rater 2 in the first reading step and after the retrospective re-evaluation of lesions that were only detected by one of the raters in the first reading. Consensus lesions were defined as lesions identified by both raters.
