Table 1 Tumor burden calculation performed for different samples using three different methods: (1) from the tumor area segmented manually in 2D images of H&E-stained specimens; (2) from the tumor area segmented using a semi-automated method and micro-CT slices of I2E-stained specimen; and (3) and tumor volume reported as the sum of measurements of all the tumorous areas of all virtual micro-CT slices.
