The high sensitivity of breast Magnetic Resonance Imaging (MRI) for detecting cancerous lesions is well established.  However, ambiguity remains in the ability of breast MRI to distinguish benign from malignant lesions and achieving consistent fat suppression in the breast often proves challenging.  Fat suppression is advantageous as cancerous lesions often originate in the glandular tissue.  Novel MRI data acquisition strategies may provide an opportunity to improve characterization of breast lesions while also improving the consistency of fat suppression.  In this work, MRI methods based on radial data acquisitions including methods for accelerating iterative fat-water separation are developed and investigated in breast MRI.  Resultant images demonstrate robust fat-water separation throughout the volume of interest and excellent depiction of morphological detail.
