The radial GRASE hybrid sequence is presented for
high-resolution Neuro-imaging at 7T. In this sequence,
the number of refocusing pulses is reduced by additional
readout gradients while keeping the number of acquired
echoes per excitation constant. The number of refocusing
pulses and thus SAR is reduced by the additional readout
gradients compared to conventional TSE sequences.
Furthermore, the radial readout allows for the
reconstruction of different T2-weighted images from one
measurement.
