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.
