,Automatic Segmentation in Abdominal CT Imaging for the KiTS21 Challenge,Net which consists of 3D Encoder-Decoder CNN architecture with additional Skip Connection is used. Lastly, there is a loss function to resolve the class imbalance problem frequently occurring in the task of medical imaging. Sørensen-Dice Score and Surface Dice Score on the test set are 80.13 and 68.61.

3D U-Net Based Semantic Segmentation of Kidneys and Renal Masses on Contrast-Enhanced CT,he majority-prediction segmentation masks. Our model achieved test-set performance of 97.0%, 85.1%, and 81.9% volumetric Dice score, and 93.7%, 72.0%, and 70.0% surface Dice score, on combined foreground, renal masses, and renal tumors, respectively, which tied for sixth place among challenge participants.
