Feasibility of deep learned reconstruction for dual-echo fast spin echo based T2 mapping of the hippocampus and hippocampal subfield

With the increased scientific interest in hippocampal subfields, a clinically applicable T2 mapping method is demanding. With a dual echo fast spin echo based approach, we were able to acquire high resolution T2 maps <5 minutes scan time. With recently introduced deep learned reconstruction, improved image quality of T2 weighted image, and T2 map is observed. Differences in measurements regarding T2 values and volumes of hippocampal subfields will be presented.
