Figure 4.

Qualitative comparisons on healthy anatomy reconstruction between UNA and state-of-the-art modality-agnostic synthesis models. Testing images are from real stroke datasets (ISLES [19] and ATLAS [31]), where the stroke lesion annotations are provided, yet the ground truth healthy anatomy is unavailable. The last row shows a failure case of UNA, where it “over-corrects” the diseased anatomy. Pathology regions are circled in red.
