摘要：
A method and system for determination of oxygen saturation in blood flowing in a vessel using magnetic resonance (MR). An MR image sequence is acquired with different echo time (TE) encoding, and different Fourier velocity encoding (FVE). A Fourier transformation is applied along the velocity dimension to determine a velocity distribution of tissue signals in each voxel of the image sequence. Tissue signals indicative of moving tissues are separated from tissue signals indicative of static tissue, based on the velocity distribution. Oxygen saturation in blood may then be determined using only the tissue signals indicative of flowing blood.
