English: Road Mapping: The top sequence illustrates conventional DSA highlighting the post-contrast image associated with maximum vessel opacification which becomes the roadmap mask. The lower sequences illustrate the result of subtracting live fluoroscopic images from the road map mask during insertion of a guidewire. The guidewire is clearly illustrated overlaid on the vasculature in direct contrast to the situation when conventional DSA is employed (see images on right).
