Lack of Anatomical Concordance between Preablation and Postablation CT Images: A Risk Factor Related to Ablation Site Recurrence
Figure 2
Similarity of Positioning Score-identical (SiPS-id). Example of identical (concordant) pre-RFA CT images and post-RFA CT images, classified as Similarity of Positioning Score-identical (SiPS-id). The pre-RFA CT scan ((a) axial, (b) coronal) and the post-RFA CT scan ((c) axial, (d) coronal) are well comparable.
