Recently, the FSE Dixon APT acquisition protocol with intrinsic B0 correction was developed and implemented on 3T clinical MRI scanners. This technique allows simultaneous acquisition of APT imaging and intrinsic B0 mapping without increasing scan time. In the present study, we demonstrated the quantitative performance of the 3D FSE Dixon APT imaging of brain tumors in comparison with the separate B0 mapping method.
