Looking inside for a diagnosis

Giving contrast to the patient allows us to see more, and allows us to reconstruct the image.  We can look at blood vessels, and overlay blood vessels without bone.  We can look for aneurysm or blockages, going to and from the brain. We can also see the whole body or just the superficial muscles.   Also, we can look at arteries of the heart to find blockages in the heart and to look at the motion of the heart.
