Abstract (en)
[origin: WO2014033163A1] The present invention relates to a device and a method for determining a value of a relative contrast-agent enhancement in the context of dynamic contrast agent MRI (e.g. DCE-MRI, DSC-MRI), said value being assigned to a time subsegment of a second time segment, on the basis of data of a subset of data from a first data record and on the basis of data of a subset of data from a second data record, where the first data record comprises data of a multidimensional k-space of a magnetic resonance recording recorded without the influence of a contrast agent and was recorded in a first time segment, wherein the second data record comprises data of a multidimensional k-space of a magnetic resonance recording recorded with the influence of a contrast agent and was recorded in the second time segment, which is different from the first time segment, wherein the data of the subset of data from the second data record are assigned to the time subsegment of the second time segment and the data of the subset of data from the first data record are assigned to substantially the same region in the k-space as the data of the subset of data from the second data record.
