Hepatic Vein and Arterial Vessel Segmentation in Liver Tumor Patients

Table 1

Arterial vessel segmentation results. Real A represents the original arterial phase CT image, and Fake B represents the venous phase CT image obtained by sending the Real A into the VRA-net. Real B represents the original venous phase CT image.

Method	Train data	Test data	Average DSC	Test data	Average DSC
2D U-net	Real A	Real A	0.8741 ± 0.0002	Real B	0.5947 ± 0.0004
3D U-net	Real A	Real A	0.8793 ± 0.0002	Real B	0.6789 ± 0.0032
2D U-net	Fake B	Fake B	0.8315 ± 0.0004	Real B	0.8117 ± 0.0013
3D U-net	Fake B	Fake B	0.8305 ± 0.0006	Real B	0.8340 ± 0.0019
Ours	Fake B	Fake B	0.8505 ± 0.0002	Real B	0.8454 ± 0.0010

Values in bold indicate that our proposed method achieves the best performance on unsupervised arterial vessel segmentation.
