Angiographic catheters are a great way to get a peek inside your body. They can be used in the heart, brain, or anywhere else in the body where a doctor would like to see what's going on.
One of the advantages of angiographic catheters is that they allow doctors to make sure everything is working correctly in the heart and blood vessels without having to perform surgery on you. They also allow doctors to take pictures of your heart and blood vessels so they can show other doctors what might need attention later down the road.
Another advantage of angiographic catheters is that they allow doctors to use contrast dyes so they can see even more clearly what's going on inside your body. The dye helps highlight certain parts of your anatomy so that it shows up better on pictures taken during an angiogram.
