Ablation study for the effect of pretrained encoder on the segmentation performance.

	Without pretrained encoder	With pretrained encoder
IoU - Jaccard index $\Uparrow$ ($\mathrm{\%}$)	75.11	80.02
Dice score $\Uparrow$ ($\mathrm{\%}$)	81.69	86.39
Hausdorff distance $\Downarrow$ (mm)	9.63	4.69
Mean surface distance $\Downarrow$ (mm)	3.82	2.11

The decoder is always initialized randomly. $\Uparrow$ indicates higher-the-better metrics, while metrics $\Downarrow$ are lower-the-better.
