Angiography

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:

  • Brain
  • Kidneys
  • Pelvis
  • Legs
  • Lungs
  • Heart
  • Neck
  • Abdomen

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)
