In-vivo validation of interpolation-based phase offset correction in cardiovascular magnetic resonance flow quantification : A multi-vendor, multi-center study
Background: A velocity offset error in phase contrast cardiovascular magnetic resonance (CMR) imaging is a known problem in clinical assessment of flow volumes in vessels around the heart. Earlier studies have shown that this offset error is clinically relevant over different systems, and cannot be removed by protocol optimization. Correction methods using phantom measurements are time consuming,
