Table 4. Intraclass Correlation Coefficient of estimated lesion volume, iodine concentration and iodine quantity.

Intraclass Correlation Coefficient of estimated sausage volumes, iodine concentrations and iodine quantities. Intraclass correlation coefficients (ICC) are calculated on three different sessions for each segmentation method. 95% CI: 95% confidence interval.
