The present invention relates to an apparatus () for presentation of dark field information. It is described to provide () an X-ray attenuation image of a region of interest of an object. A dark field X-ray image of the region of interest of the object is also provided (). A plurality of sub-regions of the region of interest are defined () based on the X-ray attenuation image of the region of interest or based on the dark field X-ray image of the region of interest. At least one quantitative value is derived () for each of the plurality of sub-regions, wherein the at least one quantitative value for a sub-region comprises data derived from the X-ray attenuation image of the sub-region and data derived from the dark field X-ray image of the sub-region. A plurality of figures of merit are assigned () to the plurality of sub-regions, wherein a figure of merit for a sub-region is based on the at least one quantitative value for the sub-region. Data representative of the region of interest is output () with figures of merit for the respective sub-regions.
