RF lesion dimensions (N = 12 lesions) correlation between measurements on real-time thermal dose maps, post-ablation T1-w images and gross pathology. Pearson’s linear correlation on (a) reformatted 2D slices from T1-w IR images and TD maps (2 dimensions per lesion, N = 24), and (b) T1-w IR images and macroscopic measurements (3 dimensions per lesion, N = 36). Dimensions are colour-coded: red for largest dimensions, blue for smallest dimensions and green for depth dimensions (b and d graphs only). It must be noted that several points correspond to more than one measure, since some lesions had identical dimensions. Pearson’s correlation coefficient R and coefficients of the linear regression are indicated on the graphs. Bland and Altman representation of the agreement between the lesion dimensions of the T1-w IR images and TD maps (c) and between the T1-w IR images and gross pathology measurements (d). Dashed lines indicate 95% confidence limits
