We have performed rapid high-resolution breast sodium MRI relaxometry using a custom sodium breast phased array coil. Clear delineation of short- and long-T2* components of the sodium signal is possible with a spatial resolution of 3.75 x 3.75 x 4mm over the entire breast with a total imaging time of under 10 min. This method will allow the investigation of the potential of sodium relaxometry to improve the specificity of breast MRI for the detection of breast cancer.
