Artifact Free 3D Fast Spin Echo Imaging Using a Single Excitation

3D Fast Spin Echo with flip angle modulation is used for high resolution T2 weighted imaging due to high T2 contrast and the ability to reformat the data in any desirable plane. Unavoidable violations of the CPMG condition due to system imperfections generate artifacts. Previously we presented a method to overcome this problem with a two excitations approach where two data sets are combined, such that scan time is twice as long. In this work we present a new stable parallel imaging method to synthesize the second data set from the first thereby reducing scan time to a single excitation.
