Claim One:
1. A method for imaging examination of an examination object, comprising: administering a contrast agent to the examination object; thereafter determining at least two spatial distributions of X-ray attenuation values, the X-ray attenuation values representing at least one of a local X-ray attenuation coefficient and variable linearly dependent thereon, the two spatial distributions including at least, a first attenuation value distribution determined on the basis of a first X-ray spectrum, a second attenuation value distribution determined on the basis of a second X-ray spectrum, differing from the first X-ray spectrum; evaluating the at least two attenuation value distributions and determining at least one of a spatial distribution of one or more predefined atomic number values and a spatial distribution of non-predefined atomic number values present in the examination object, the spatial distribution including information relating to the distribution of the administered contrast agent in the examination object; and using the spatial atomic number distribution to represent the contrast agent by imaging.
