Radiomics is a technique method of utilizing the high-throughput extraction of features from medical images to achieve tumor segmentation, feature extraction and model foundation. It could assist the clinical diagnosis and treatment of tumors by mining, analyzing and predicting a large amount of deep data information. In the era of precision medicine, the early individual diagnosis and treatment of breast cancer (BC) are especially important.Conventional ultrasound is an important imaging method for the diagnosis of breast tumors.Contrast-enhanced ultrasound (CEUS) can reflect the morphological and functional changes of microvascular perfusion of breast tumors in real time. On the basis of conventional ultrasound and CEUS, the radiomics has potential of clinical application in the differential diagnosis of benign and malignant breast tumors and molecular classification of breast cancer. This paper reviews the correlation between conventional ultrasound combined with CEUS radiomics features of breast tumors and breast cancer molecular typing of breast cancer.
