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
