Abstract
A method is for determining at least one first characteristic value of blood in a patient. In an embodiment, the method includes acquiring, via a computed tomography device, computed tomography data of the patient for at least two energy levels of radiation using multi-energy computed tomography; defining a region of interest including blood, in at least one image data set reconstructed from the computed tomography data acquired; determining, at least in the region of interest defined, attenuation coefficients for each energy level of the at least two energy levels; performing material decomposition into at least two materials, one material of the two materials being iron, using the attenuation coefficients determined, yielding at least a fraction of iron in the region of interest defined; and determining the at least one first characteristic value, at least one of as and from the fraction of iron yielded.
