Flow quantification on uncooperative patients that cannot hold their breath may be performed by real-time free-breathing flow acquisitions that generally cover multiple heart-beats. However, heart-rate fluctuations, low SNR, and respiratory motion associated with such acquisitions may impede flow quantification process. In this study, we are extending our unsupervised motion correction method for real-time free-breathing cine imaging to flow imaging, and comparing the results with gold standard ECG gated, breath-held, segmented flow acquisition. Preliminary results indicate net forward volumes in agreement with the reference, with comparable image quality.
