Figure 4. Qualitative comparison of two representative cases: complex anatomy (Example 1) and sparse anatomy (Example 2), showing (top to bottom) ground truth, baseline Swin UNETR, and two enhanced models. Black boxes report the median Dice scores for each method. Enhanced outputs exhibit markedly improved branch continuity and reduced false‑positive suppression. Swin UNETR: Swin UNEt TRansformers.
