Vessel wall MRI requires good fat suppression to delineate outer vessel boundaries. Large field-of-views required for turbo spin echo femoral vessel wall MRI do not provide good fat suppression with spectral inversion recovery. We developed a time-efficient two-point Dixon turbo spin echo method using a SNR priority variable flip angle schedule and point spread correction reconstruction to allow accelerated acquisition and demonstrate its advantages compared to an existing gradient echo vessel wall MRI method.
