Breast tissue conductivity map based on EPT MRI is one of the non-contrast methods that can differentiate malignant from benign breast lesions; however, the need for DCE based tumor “mask” to generate conductivity maps from the phase of VISTA images in breast challenges EPT’s role as a non-contrast method. This study demonstrates an alternative to reconstruct breast tissue conductivity maps using T2-w mDixon TSE sequence that is comparable with DCE/VISTA method, and demonstrates similarities in detecting cancerous tissues. EPT maps of breast using T2-w mDixon TSE method has the potential to help in developing non-contrast MR breast cancer screening protocol.
