An alternate-cycle acquisition strategy is proposed for 3D whole-heart first-pass perfusion, capturing two separate datasets from the same first-pass, each pushing separate boundaries of currently achievable parameters whilst maintaining clinically feasible acquisition times. It is postulated this approach may also confer an advantage with regard to artefact detection.
