Previous studies have used the T2WI- and DCE-based radiomics features to preoperatively predict the muscle-invasive status and pathological grade in BCa [20, 21], suggesting that the T2WI- and DCE-based radiomics features can indicate the biological behavior and heterogeneity on the onset of tumor and may facilitate the application of T2WI- and DCE-based radiomics features for Ki67 expression prediction in BCa. The gene discussed is MKI67; the disease is neoplasm.
