(44) used radiomics model based on two-dimensional ultrasound images and combined models based on ultrasound images and clinical information to predict Ki-67 expression in invasive ductal carcinoma of breast cancer, The basic model’s test set AUC was 0.710, while the combined model’s AUC increased to 0.770. The gene discussed is MKI67; the disease is invasive ductal breast carcinoma.
