Abstract
A method for determining a concentration of a contrast agent in imaging data includes calculating a pre-contrast attenuation map of a region of interest of a patient. Following an administering of a contrast agent to the patient, a post-contrast attenuation map of the region of interest of the patient is calculated. An increase in attenuation value is determined based on the pre-contrast attenuation map and the post-contrast attenuation map and a contrast agent concentration map is calculated for the region of interest based on the increase in attenuation value.
