Angiography is a diagnostic method performed with X-rays to evaluate the health of blood vessels. It involves using a contrast agent, as the blood vessels are not visible during an X-ray. However, the blood vessels are visible during X-rays once the contrast agent is injected.
Most patients undergoing angiography experience only a little discomfort when the contrast agent is injected into the vessels. However, in some cases, the patients may also experience infection, swelling at the injection site, vascular damage, and radiation injury.
Angiography is a diagnostic test that detects the presence of any blockage in the arteries. The doctors may simultaneously open the blockage with athe treatment intervention known as angioplasty.
