A double-ablation zone created by overlapping ablation spheres by 58% of their diameter (interval between electrode tips: 1.7 cm).
A. Photograph of longitudinal section of the elliptical specimen depicts an ablation zone measuring 6.4 cm transversely and 4.2 cm longitudinally.
B. T2-weighted FSE (TR 3084/TE 104) coronal image shows a low-signal zone (arrows).
C. Three-dimensional ablation zone reconstructed from MR images appears as an irregularly contoured composite oval shape.
