The present invention relates to vascular treatment outcome visualization. To provide an enhanced possibility to check that a vascular treatment has been correctly performed, it is proposed to provide (112) a first image data (114) of a region of interest of a vascular structure at a first point in time, and to provide (116) at least one second image data (118) of the region of interest of the vascular structure at a second point in time, wherein a vascular treatment has been applied to the vascular structure between the first point in time and the second point in time. Further, the first and the at least one second image data are combined (120) generating a joint outcome visualization image data (122) and the joint outcome visualization image data is displayed (124).
