Fast (or Turbo) spin echo (FSE, TSE) pulse sequences are widely used in clinical imaging but they suffer from blurring when high spatial frequencies are attenuated by T2-effects. This blurring is especially pronounced at high field when T2 is shorter. We have developed a method to reduce blurring effects using an appropriate point spread function (PSF) measured by a modified TSE sequence but without deconvolution. The method restores image sharpness at reasonable additional scan times.
