Breast magnetic resonance elastography: a review of clinical work and future perspectives

Abstract

This review on magnetic resonance elastography (MRE) of the breast provides an overview of available literature and describes current developments in the field of breast MRE, including new transducer technology for data acquisition and multi-frequency-derived power-law behaviour of tissue. Moreover, we discuss the future potential of breast MRE, which goes beyond its original application as an additional tool in differentiating benign from malignant breast lesions. These areas of ongoing and future research include MRE for pre-operative tumour delineation, staging, monitoring and predicting response to treatment, as well as prediction of the metastatic potential of primary tumours.

Keywords: MRI; breast cancer; magnetic resonance elastography (MRE); multi-frequency; octahedral shear strain; ultrasound elastography.
