A method and an apparatus are disclosed for visualizing deposits in blood vessels, particularly in coronary vessels. In such a method, 2D slice images may be reconstructed from the measurement data, with image data of the 2D slice images being post-processed for local determination of brightness values and/or of default values on which these are based in the 2D slice images. In the presentation of the 2D slice images, one or more image areas are marked in which, in the post-processing, pixels are automatically color-coded and presented according to a predeterminable transfer function which assigns different colors to different value ranges of brightness values and/or of default values on which these are based.
