Echo-planar imaging#
One excitation followed by a train of readout lobes of alternating polarity with phase-encode blips, so several phase-encode lines are acquired after each excitation and off-resonance phase accumulates along the phase-encode axis.

Scope |
|---|---|
One blipped echo train per excitation, with segmentation and in-plane acceleration compared by echo-train length and distortion. |
|
The CAIPIRINHA lattice and its skipped-CAIPI traversal, single-shot and segmented. |
