Abstract:
A dual magnetic resonance imaging method simultaneously acquires a first and a second time series of MR images wherein the temporal resolution of the first time series of images is larger than that of the second time series while the spatial resolution of the first time series of images is smaller than that of the second time series. Accordingly, in the context of DCE-MRI, the first time series can be used to determine the arterial input function (AIF) while the second time series can be used to determine the concentration time course in the tissue of interest, e.g. in a vessel wall. Therefore, both the AIF and the tissue time course can be acquired with their optimal dynamic signal range.
