A computer-implemented method for evaluating an X-ray image includes: segmenting the hollow organ structure in the X-ray image; determining center lines and edge boundaries of the segmented hollow organ structure and ascertaining a diameter of each hollow organ along its center line; ascertaining an image absorption value, describing the increase in absorption due to a contrast agent in the hollow organ compared to surroundings of the hollow organ, along the center line of each hollow organ; ascertaining, for each image absorption value, a theoretical computing absorption value expected when the hollow organ is completely filled with the contrast agent, by using at least the diameter and contrast agent information; determining a filling level along the center line of each hollow organ of the hollow organ structure by comparing the image absorption value with the computing absorption value; and outputting filling level information including the filling levels.
