A new flow quantification measured is proposed. Multi-echo gradient echo sequence is used for data acquisition. Polynomial fit of multi-echo phase data is used to extract field inhomogeneity information. Coefficient of the fit is directly related to flow velocity. Thus by changing the background field inhomogeneity, flow could be quantified. This method is validated in phantom and in vivo experiments.
