For more information or to see if angiography may be right for you, please check with your primary care physician.
Angiography is a minimally invasive medical test that helps physicians diagnose and treat medical conditions. Angiography uses one of three imaging technologies and, in some cases, a contrast material to produce pictures of major blood vessels throughout the body.
Angiography is performed using:
- x-rays with catheters
- computed tomography (CT)
- magnetic resonance imaging (MRI)
In catheter angiography, a thin plastic tube, called a catheter, is inserted into an artery through a small incision in the skin. Once the catheter is guided to the area being examined, a contrast material is injected through the tube and images are captured using a small dose of x-ray.
Catheter angiography is used to examine blood vessels in key areas of the body, including the:
Common Uses for Angiography
- identify disease and aneurysms in the aorta, both in the chest and abdomen, or in other major blood vessels
- detect atherosclerotic disease in the carotid artery of the neck, which may limit blood flow to the brain and cause a stroke
- identify a small aneurysm or arteriovenous malformations inside the brain
- detect atherosclerotic disease that has narrowed the arteries to the legs and help prepare for endovascular intervention or surgery
- detect disease in the arteries to the kidneys or visualize blood flow to help prepare for a kidney transplant
- guide interventional radiologists and surgeons making repairs to diseased blood vessels, such as implanting stents or evaluating a stent after implantation
- detect injury to one of more arteries in the neck, chest, abdomen, pelvis or extremities in trauma patients
- evaluate arteries feeding a tumor prior to surgery or other procedures such as chemoembolization or selective internal radiation therapy
- identify dissection or splitting in the aorta in the chest or abdomen or its major branches.
- show the extent and severity of atherosclerosis in the coronary arteries and plan for a surgical operation, such as a coronary bypass and stenting
- sample blood from specific veins in the body to detect any endocrine disease
- examine pulmonary arteries in the lungs to detect pulmonary embolism (blood clots from leg veins)
