MR imaging with shortest possible acquisition times is targeted by single-shot spiral readouts and extremely rapid gradient encoding. The implementation involves a first demonstration of spiral imaging using a gradient insert to achieve a slew rate of 1200 T/m/s. The achievable imaging performance is evaluated and in-vivo results are presented. The setup permitted imaging with more than 280 frames per second, which also allowed the extraction of rudimentary spectral imaging information from a single MR readout. The newly available temporal resolution in MR may be utilized to gain new insights in brain function and physiology.
