Accurate flow measurements are difficult to obtain within the time of a patients breathhold. Previous studies using a cine PC undersampled projection reconstruction (PRPC) technique have shown that accurate flow measurements can be obtained in the time of a breathhold. In this study we used a swine model to evaluate the PRPC technique in comparison with a Fourier-based PC acquisition. Flow measurements in the aorta and renal arteries correlated well between the two methods. Undersampled PRPC offers benefits over the Fourier-based method, which may provide increased ability to evaluate the hemodynamic significance of stenoses for improved treatment planning.
