Angiography is the imaging of the blood vessels of an organ. In pulmonary angiography, the arteries and veins of the lungs are viewed. A special dye is injected into the blood vessel, and imaging is done. This helps in diagnosing clots in blood vessels and narrowing the blood vessels that take blood to the lungs. The most common side effects are allergic reaction to the dye, hematoma, injury to the nerve, etc.
