Fig 2. — IPVL segment volumes that are highly analogous to operator-defined volumes. Results from 4 subjects representing the highest and lowest Dice similarity coefficient scores for CEV and FHV segmentations are shown. A, The highest DICE (top) and lowest DICE (bottom) examples of IPVL-segmented CEVs relative to operator-defined volumes are shown. The corresponding FHV segmentation results are shown (right) to demonstrate that CEV segmentations are independent of FHV segmentations. B, The highest DICE (top) and lowest DICE (bottom) examples of IPVL-segmented FHV relative to operator-defined volumes are shown. The corresponding CEV segmentation results are shown as well (right) to demonstrate that FHV segmentations are independent of CEV segmentations. Yellow indicates regions of intersection between operator and IPVL-defined volumes; red, operator-defined volume only; green, IPVL-defined volume only. Corresponding CEV segmentations are overlaid in blue on FLAIR images for clarity.
