Fully self-gated respiratory and cardiac motion-resolved 5D flow: comparison at 1.5T and 3T

Video Transcription

Video Summary

Mariana Falcão presented 5DFlow, a fully self-gated whole-heart 3D radial MRI method that captures respiratory and cardiac motion during scanning to reconstruct flow images by phase. In a study of 11 healthy volunteers scanned at both 1.5T and 3T, her team compared self-gating quality and flow measurements against conventional 4DFlow MRI. Results showed similar triggering variability at both field strengths, with 3T generally matching 4DFlow slightly better than 1.5T. The work suggests higher SNR at 3T may improve flow assessment, though patient studies are still needed.
