Table 2 Inter- and Intra-observer variability. The upper part of the table lists the results from the agreement analysis, based on absolute differences between the ROI sets. The lower part of the table depicts the consistency analysis, based on an ICC (Winer’s adjustment for anchor points). No significant difference was found among the sequences
