Fast spin echo acquisition (FSE) plays a central role in clinical MRI. A major limitation to this approach is that T2 decay during multiple echoes acquisition can result in image blurring. Methods based on flip angle modulation have been reported to address this problem so that long echo train can be used to achieve high SNR efficiency in 3D imaging without excessive image blurring. In this work, we reported an efficient approach to further reduce the blurring in such advanced 3D FSE imaging methods based on deconvolution of k-space.
