Comparison of achieved and expected ablation volumes for manually planned and implemented trajectories
| Structure | Achieved manual trajectory ROI ablation | Expected manual trajectory ROI ablation | Estimation error as proportion of anatomical volume (%) |
|---|---|---|---|
| Amygdala | 741.92 ± 423.93 | 739.84 ± 372.29 | −2.08 |
| Hippocampus | 1630.32 ± 580.90 | 2003.28 ± 565.33 | +12.49 |
| AHC | 2510.54 ± 887.46 | 2748.30 ± 771.30 | +4.96 |
| ENCx | 269.23 ± 368.17 | 246.85 ± 271.41 | −0.97 |
| PHG | 478.87 ± 447.05 | 621.94 ± 495.06 | +4.73 |
| Total ROIs | 3258.59 ± 1351.81 | 3686.26 ± 959.25 | +4.22 |
Expected ablation volumes are those modeled using a 15‐mm‐diameter symmetrical ablation zone. Error for each structure is calculated as a proportion of the anatomical volume at baseline. AHC, amygdalohippocampal complex; ENCx, entorhinal cortex; PHG, parahippocampal gyrus; ROI, region of interest.
