The main purpose of this phantom study is to assess the influence of k-t Principal Component Analysis reconstruction technique on the 4D PC-MRI velocity measurements through millimetrics vessels. 4D PC-MRI sequence is repeated 4 times with a k-t PCA acceleration factor set at 0, 2, 4 and 8. Flow curves are reconstructed and their mean flow and amplitude are compared. Results shows it is possible to reduce the acquisition time and still maintain a good mean flow measurement accuracy. However, the k-t PCA acceleration factor causes loss of information, resulting in a decrease of the amplitude of the flow curve.
