  1. Results of two sub-tasks are reported, separated by a double horizontal line, for the segmentation of a single label (whole lesion, Task 1.1) and three separate labels (Task 1.2). Results are reported separately for all test cases (full, 53 images), and for pre-treatment images only (15 images).
