Lack of Anatomical Concordance between Preablation and Postablation CT Images: A Risk Factor Related to Ablation Site Recurrence
Figure 3
Similarity of Positioning Score-different (SiPS-diff). Example of nonidentical (discordant) pre-RFA CT-images and post-RFA CT-images, classified as Similarity of Positioning Score-different (SiPS-diff). The pre-RFA CT-scan ((a) axial, (b) coronal) and post-RFA CT-scan ((c) axial, (d) coronal) are not comparable.
