Spiral Fast Spin Echo MRI with Interleaved Diffusion Sensitization for Simultaneous ADC and T2 Mapping

A sequence design is presented based on spiral fast spin echo acquisition with interleaved diffusion sensitization for simultaneous ADC and T2 mapping. With spiral readout trajectories only few echoes need to be acquired per (TE,b) pair allowing to accelerate the acquisition significantly. A phantom experiment with single echo per k-space is shown for T2 and ADC mapping. With a model-based reconstruction both parameter maps can be rapidly reconstructed.
