1. A vascular roadmapping apparatus for visualizing an image of an instrument, said image including an anatomy part in which said instrument is disposed, said apparatus comprising a vascular roadmapping processor configured for: receiving a contrast-enhanced image of said anatomy part, without said contrast-enhanced image having been subjected to blood vessel segmentation that operates, on a contrast-enhanced image in preparation for roadmapping, by deducing a cardiac roadmap although retaining less than a full angiogram; receiving a fluoroscopy image that includes depiction of, in said anatomy part, said instrument; defining an area of said fluoroscopy image in which area at least a portion of said instrument, and a region that surrounds said portion but excludes the instrument itself, are included; and, combining the defined area of said fluoroscopy image with the received contrast-enhanced image, without prior performance of said segmentation on the received contrast-enhanced image, said combining overlaying said area onto said received contrast-enhanced image.
