The present invention relates to use of co-registered data to virtually recreate a section of a vessel in an external image, in which the section of the vessel cannot be imaged using an external imaging modality. In certain aspects, a method of the invention includes obtaining external imaging data of a vessel, wherein data representing a specific portion of the vessel is absent from the external imaging data, obtaining intraluminal imaging data of the specific portion of the vessel, and co-registering the external imaging data with the intraluminal imaging data to construct an external image of the vessel that includes the specific portion of the vessel.
