ABSTRACT
CEUS is a pure blood pool imaging depending on the non-linear effect and strong backscatter of gas-filled microbubbles in blood to obtain contrast-enhanced images.With the advantages of displaying tumor microvascular dynamically and intuitively,CEUS has been widely used for diagnosis and evaluating prognosis of breast cancers.CEUShas high sensitivity and specificity in detecting early breast cancers and identifying sentinel lymph nodes,with wide application prospects in assessing the efficacy of neoadjuvant therapy,predicting molecular typing and targeted therapy of breast cancers.The features of CEUS in breast cancers and the relationships with biomarkers,progresses in assessing neoadjuvant therapy and assisting sentinel lymph node biopsy were reviewed in the article.
