摘要：
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.
