The aim of this study is to compare a high spatial resolution 2D PC-MRI protocol with a 4D PC-MRI protocol in a phantom with calibrated thin tubes and physiological oscillating flows. Protocols were applied on the phantom in a 3T, Achieva dStream, Philips using 32 head coils channels. Accuracy of the flow measurement was then evaluated by calculating the difference between expected and measured flow in each branches. For both sequences we had an error less than 10%, however 2D PC-MRI measurement was more accurate. It is possible to have 4D PC-MRI flow measurement consistent with 2D PC-MRI measurement
