In breast DWI, typically EPI based methods are used which are prone to characteristic artifacts, such as spatial distortion due to gradient nonlinearity or eddy currents. This study demonstrates the use of 2D-selective RF excitation from a 2-channel parallel transmit system (pTX) to a) overcome these distortions and b) allow the user to restrict the acquisition volume to the breast alone (zoomed EPI).
