Table 4.

Reader agreement based on intra-class correlation coefficients. The scale of Koo/Li was used for interpretation [28]. Results are depicted as k-values with 95% confidence intervals (95% CI).

Criterion	k-Value	95% CI	Koo/Li-Scale
Overall	0.810	0.731–0.871	good
Quality of the registration	0.772	0.574–0.906	good
Ablation zone movement	0.774	0.580–0.907	good
Ablation probe movement	0.880	0.768–0.952	good
Tissue distortion	0.335	−0.047–0.691	poor
Image artifacts	0.524	0.194–0.792	moderate
