Breast cancer is one most common cancer in female worldwide. Ki-67 index is an significant biomarker whose expression status is closely related with response to chemotherapy and the disease prognosis in patients with breast cancer. This study retrospectively investigated the relationship between DCE-MRI features and Ki-67 status in breast carcinoma. The results indicated the type of washout TIC and heterogeneous type of reinforcement is more common in high Ki-67 status in patients with breast cancer. The DCE-MRI imaging features can non-invasively assess Ki-67 status in breast carcinoma before surgery.
