This work looks at the feasibility of performing sparse sampling in high resolution phase contrast imaging using a CS-SENSE reconstruction algorithm. Images were simulated at 25, 18, and 14% sparse acquisition and compared against a clinical acquired dataset through region of interest analysis. Undersampled data showed slight underestimation of quantitative values while still maintaining an accurate flow curve behavior. The intrinsic nature of undersampling most likely leads to quantitative discrepancy. CS-SENSE is shown to be feasible and promising achieving accurate quantitative data.
