For high resolution images of the human brain a hybrid
sequence with a radial readout is presented. In this
technique gradient refocused echoes replace refocusing
radio-frequency pulses up to a certain level. This
offers a significant SAR-reduced imaging compared to a
turbo-spin-echo technique with the same
echo-train-length. The radial k-space acquisition and a
view-sharing technique (KWIC) for the reconstruction,
allow several arbitrary T2-weighted images. High
resolution in-vivo human brain images are presented.
