Heavily T2-weighted imaging is used for a variety of fluid sensitive imaging such as MRCP. However, these fast spin-echo-based methods suffer from long acquisition duration. In this work we apply a novel strategy using RF phase modulated gradient echo (GRE) with small RF phase increments to encode T2 information into the phase of the signal. In this work, we optimize this strategy for long T2 species to achieve heavily T2-weighted imaging, including the introduction of a novel cross-product strategy to highlight signal in tissues with long T2 and suppress signal in tissues with shorter T2 values.
