Most of previous studies also focused on MRI-based radiomics features to predict the Ki-67 expression status in various tumors, including liver cancer [33], thyroid cancer [31], glioma [34] and breast cancer [30, 36], which suggests that MRI-based radiomics features have the potential to predict the Ki67 expression status in BCa. Here, MKI67 is linked to thyroid gland carcinoma.
