20090232410 | MR METHOD FOR SPATIALLY-RESOLVED DETERMINATION OF RELAXATION PARAMETERS - The invention relates to an MR method for spatially resolved determination of relaxation parameters in an examination zone, comprising the steps: a. acquisition, by means of a first sequence, of MR data sets for a plurality of MR images having different echo times, b. acquisition, by means of a second sequence, of at least one further MR data set for at least one further MR image having an enhanced spatial resolution and reduced time resolution in comparison with the MR images of the first sequence, c. generation of MR combination images using an MR data set derived from the first sequence for a portion within the k-space and the MR data of a further MR data set acquired outside this portion by means of the second sequence, d. derivation of relaxation parameters from the MR combination images. | 09-17-2009 |

20080197843 | Determination Of Relaxation Rate Changes For Mr Molecular Imaging - MR based molecular imaging is strongly supported by the accurate quantification of contrast agents. According to an exemplary embodiment of the present invention, a determination unit of an examination apparatus is adapted for determining an error propagation function, wherein the error propagation function is then used as a weighting function for an accurate determination Of AR | 08-21-2008 |
