Phase contrast (PC) cardiac MRI is clinically used to quantify flow. The quantification accuracy is diminished by background phase errors. Stationary tissue-based background phase correction algorithms are commercially available, but their accuracy is still under evaluation. Here, we investigate if a self-calibrated phase contrast (SCPC) algorithm which includes automatic failure mode classification, can improve accuracy in a large single-vendor multi-scanner study including 346 PC scans. Our results show that SCPC improves flow quantification accuracy and can identify most PC scans which are unreliable regardless of stationary tissue correction or not.
