Patent application numberDescriptionPublished
20080197843Determination 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 AR08-21-2008
20080272779Determination of Distribution Information of a Contrast Agent by Mr Molecular Imaging - MR based molecular imaging is used for the quantification of contrast agent concentrations. According to an exemplary embodiment of the present invention, a difference between R2 and R2* relaxation rates of a contrast agent is determined on the basis of data measured after contrast agent application. This may provide for an in vivo information relating to a compartmentalization or binding status of the contrast agent, and thus may improve the significance of the examination result.11-06-2008
20090080750PASSIVE MR VISUALISATION OF INTERVENTIONAL INSTRUMENTS - The invention relates to a device for magnetic resonance imaging of a body (03-26-2009
20090111140SYSTEMS AND METHODS FOR CELL MEASUREMENT UTILIZING ULTRASHORT T2* - The present disclosure is directed to a new technique for MR measurement of ultrashort T04-30-2009
20090130023Multiple Contrast Agent Injection For Imaging - MRI based molecular imaging is strongly supported by the accurate quantification of contrast agents. According to an exemplary embodiment of the present invention, contrast agent is applied on the basis of a multiple injection application scheme, during which changes in relaxation rate are determined. This may provide for an accurate determination of tumor vascularity via MRI relaxometry.05-21-2009
20090131781DETERMINATION OF SUSCEPTIBILITY-INDUCED MAGNETIC FIELD GRADIENTS BY MAGNETIC RESONANCE - The invention relates to a device for magnetic resonance imaging of a body (05-21-2009
20090232410MR 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
20100002926DETERMINATION OF SUSCEPTIBILITY-INDUCED MAGNETIC FIELD GRADIENTS BY MAGNETIC RESONANCE - The invention relates to a device for magnetic resonance imaging of a body (01-07-2010
