Abstract: Baseline offset errors on phase-contrast velocity images can be corrected using stationary tissue, for example sub- tracting fitted corrections from the image (1). Although corrections are often curved over the FOV, 1st order (linear) fitting is typical. This may partly be due to low SNR of static tissue making hig her-order fitting unreli- able (2). Aim: To evaluate a new method acquiring addi- tional high SNR velocity ima ges specifically to improve offset correction.
