A Novel Approach to Phase-Contrast Velocity Offset Correction by in-vivo High-SNR Acquisitions

Merlin Fair¹, Peter David Gatehouse¹, Peter Drivas¹, David N. Firmin¹

A modified phase-contrast method gave increased SNR for static tissue for baseline velocity offset correction, using one extra breath-hold after each flow study. In 18 flow studies, this improved accuracy in offset corrections using higher order fits, but gave no significant improvement over the standard linear correction of background offsets.
