Method for examining a living subject by non-invasive imaging employing a contrast agent

摘要

In a method for examining a living subject with an imaging method making use of the concentration of a contrast agent having a physical property that is identifiable with the imaging method in a region of interest (ROI) of the subject presented in time-successive images acquired with the imaging method representing quantitative values of the physical property, a histogram of the quantitative values of the physical property in the ROI is produced for each of the individual images, and the contrast agent concentration in the ROI is determined on the basis of the frequency of occurrence of the quantitative values of the physical property in the ROI.
