Early enhancement in breast DCE-MRI is very sparse, if the FOV is reduced in these images and aliasing occurs, the likelihood that two significantly enhancing voxels overlap is low. We present a method for ‘unfolding’ of aliased DCE-MRI acquisitions that closely approximates fully-sampled acquisitions. This method could be used to increase the temporal resolution of DCE-MRI at very early times when enhancement is rapidly changing, allowing for the accurate measurement of early lesion kinetics.
