Angiography is an x-ray study of a patient’s blood vessels.
The angiogram uses a type of contrast so that the patient’s blood vessels are visible when an x-ray is taken.
Most radiographic contrasts use iodine as a key ingredient.
This test is used by doctors to look for problems in the blood vessels, such as blockages and narrowing in a person’s blood vessels.
It’s often looked at in organs and throughout a patient’s circulatory system.
This procedure is often used to look for different problems a patient might have, such as diagnosing heart disease, atherosclerosis, evaluating functions of the kidneys, mapping anatomy of the renal area in donors for transplants, to look for an aneurysm, a tumor, blood clot, or an abnormal tangle of veins and arteries in a patient’s brain, and to look for and diagnose any problems that a patient has with the retina of their eye.
Surgeons also use it as a vascular map of a patient’s heart before performing open-heart surgery.
It is also used to look at a person’s brain before neurosurgery.
If the patient has had penetrating trauma, such as a knife wound or a gunshot, it can be used to see whether there is an injury to blood vessels.
