Keywords: Flow, Valves, regurgitation
Motivation: MRI is not capable of measuring tricuspid regurgitant jets, required for diastolic function evaluation.
Goal(s): Using a dynamic slice plane which tracked the tricuspid valve, we studied patients with suspected tricuspid regurgitation.
Approach: The valve-tracking phase-contrast sequence used deep learning to automatically prescribe a phase-dependent slice plane.
Results: Tricuspid regurgitation was measured and tricuspid regurgitant jets could be visualized in patients.
Impact: A new automated 2D valve-tracking phase-contrast approach permits visualization of tricuspid regurgitant jets. This will enable evaluation of diastolic function by MRI.
