Free gradient waveforms for diffusion MRI offer new insights in the underlying microstructure compared the classical Stejskal-Tanner linear encoding. A drawback of this approach is the prolonged echo time and thus decreased SNR. Here we present an approach to shorten the echo time by employing spiral readouts instead of echo-planar imaging and using the ultra-strong gradients of the Connectom scanner. The feasibility of this approach is demonstrated in a biomimetic phantom.
