One of the most common angiograms performed is to visualize the blood in thecoronary arteries. A long, thin, flexible tube called a catheter is used to administer the X-ray contrast agent at the desired area to be visualized. The catheter is threaded into an artery in the forearm, and the tip is advanced through the arterial system into the major coronary artery.
Note to self- would be cool to have a section about blood that goes along with this, where we shoot the film in x-ray and show different parts of the body moving and touching, the hidden revealed etc. Blood as a metaphor.
