The 3D FSE sequence is widely used in clinical MRI for its capability to collect many phase encoding lines in each RF excitation. However, the signals during the long echo train readout are modulated by the T2 decay, resulting in blurring. An algorithm is presented to retrospectively demodulate estimated T2 decay from the actual signal. In the preliminary data, the proposed algorithm demonstrated success in deblurring the images.
