If you need to have an angiogram, you will be asked to lie on a table and a very thin, flexible tube will be inserted into a blood vessel in your upper leg near the groin. The tube is carefully moved through your blood vessels until it's near your liver. A special dye is then put into the liver's blood vessels. The dye shows up on x-ray pictures that are taken of the liver and its blood vessels.

Your healthcare provider can look at these pictures to see the size, position, and appearance of your liver.

If you need to have an angiogram, the entire process usually takes about an hour.
