Abstract

Method for determining at least one first characteristic value of blood in a patient, the at least one first characteristic value describing the iron content of the blood, characterised in that- in a computed tomography device (17), computed tomography data of the patient for at least two energy levels of radiation is acquired using multi energy computed tomography,- a region of interest (2) comprising blood is defined in at least one image data set reconstructed from the computed tomography data,- at least in the region of interest (2), attenuation coefficients are determined for each energy level,- material decomposition into at least two materials, one material being iron, is performed using the attenuation coefficients, yielding at least a fraction of iron in the region of interest (2), and- the first characteristic value is determined as and/or from the iron fraction.
