I am working on acquiring fully sampled low-res spiral pre-scans for my spiral sequence. To estimate B0-maps, I use a dual echo readout (2 spiral out trajectories) with a rephasing lobe between the echoes. I saw that one of the axes was not rephased in my initial imaging experiments [panel A]. This was due to an error in calculating the rephasing moment which I missed in the sequence simulation. Being able to directly visualize the gradient moments made it easy to identify the error and fix the calculation in the pulse sequence [panel B].
