A novel k-space trajectory in 3D GRASE has achieved T2* weighted contrast without requiring preparation pulses, or violation of the CPMG condition by means of shifting the order of phase encoding so that ko and central k-space does not fall upon spin echoes. The technique has achieved single-shot 3D GRASE images with T2* and BOLD contrast as evaluated at 1.5T and 3T imaging with a motor task paradigm.
