Abstract
The invention relates to a method of Computed Tomography imaging comprising: a. Performing a single acquisition of image data from at least two contrast agents into a blood vessel network, a first contrast agent among said at least two contrast agents having been in said blood vessel network for a longer time than a second contrast agent among said at least two contrast agents, b. Processing said image data using K-Edge detection and/or iodine delineation to separate data associated with each contrast agents in order to obtain a concentration map of each contrast agent, c. Determining from said image data a first part of the blood vessel network comprising both the first contrast agent and the second contrast agent, and a second part of the blood vessel network comprising only the first contrast agent, d. Calculating a partial blood volume map of the first part of the blood vessel network based on the total amount of second contrast agent and on the concentration map of the second contrast agent, e. Calculating a partial blood volume map of the second part of the blood vessel network based on the total amount of first contrast agent, on the concentration map of the first contrast agent and on the partial blood volume map of the first part of the blood vessel network.
