Prospective gating
Can anyone explain the advantages and disadvantages of prospective vs. retrospective gating? It seems that prospective is generally faster, but I am not sure why if you the same number of phase encoding steps for a particular frame of the cardiac cycle.

RE: Prospective gating
For a patient with a uniform heartbeat, there would be no difference in acquisition times between prospective and retrospective gating. For irregular heartbeats, many views would be rejected because they wouldn't fit in the acquisition window for prospective gating, so the acquisition would be longer.
