Purpose To correct background phase errors in phase‐contrast magnetic resonance imaging (MRI), image‐based correction by referencing through stationary tissue is widely used. The aim of the present study was a detailed assessment of background phase errors in 4D Flow MRI and limitations of image‐bas...
