Fig. 5From: Artificial intelligence-assisted interpretation of Ki-67 expression and repeatability in breast cancerDistribution of breast cancer Ki-67 positive tumor cells (10×). A: Breast cancer Ki-67 positive tumor cells are unevenly distributed, which is heterogeneous. The percentage of Ki-67 positive tumor cells on the left is lower than that on the right (hot spot); B: Ki-67 positive tumor cells of breast cancer are uniformly distributed, showing homogeneityBack to article page
