In this work, we incorporate Pilot Tone as part of our previously described highly accelerated and fully self-gated 4D flow framework to perform retrospective cardiac binning. We compare cardiac triggers derived from Pilot Tone directly with those derived from self-gating and ECG in and demonstrate agreement in aortic and pulmonary artery flow quantification between 4D flow images reconstructed us ECG-, SG-, and PT-based cardiac binning.
