We combine the recently proposed Pilot Tone technology with our previously described highly accelerated fully self-gated whole heart 4D flow framework. We demonstrate good agreement in flow quantification between 4D flow images reconstructed us ECG-, SG-, and PT-based cardiac binning.
Figure 1. Example
ECG, SG, and PT signal traces with corresponding cardiac triggers from a
healthy volunteer (Volunteer 1). A 30 second window is shown for clarity.
Figure 2. Bland-Altman plots comparing net volumetric flow,
Q, quantified from the ECG-, SG-, and PT-binned 4D flow reconstructions with
respect to the 2D-PC reference. Biases and limits-of-agreement (LOAs) were
computed from the aggregate of Aao and MPA measurements. The y-axis is in terms
of milliliters.
