As an emerging technology, radiomics has shown potential values in the field of healthcare. CT/MRI was preferred in previous radiomics researches because its images are easy to be standardized. And only until recently, an increasing number of studies focusing on the application of ultrasound radiomics in predicting molecular subtypes, identifying of malignant lesions, reactions to neoadjuvant chemotherapy, and axillary lymph node metastasis of breast cancer have been published. The purpose of this review is to summarize the steps of radiomics used in the field of breast cancer. In conclusion, ultrasound radiomics is a promising technology in diagnosing and monitoring breast cancer and further assisting physicians in patient management.
