No uniform consensus on the optimal sampling resolution for quantitative DCE MRI exists. In order to increase the sampling resolution, accelerated parallel imaging techniques (PAT) can be used. The inter- and intra-measurement precision of the plasma flow (PF) was determined in a phantom depending on the sampling resolution (1.9-3.8s), achieved by varying the PAT factor (1-6). A significant influence of the PAT factors and the sampling resolution on the PF itself and the robustness and reproducibility of the fit could be observed, even with small sampling rates as recommended in literature.
