Angiography is a series of X-ray images taken after injection of contrast material (dye) into arteries which makes the blood vessels visible. The skilled radiologists at Queen’s Imaging can look for unusual narrowing of the artery, and blockage or weakness in the arterial wall. This information is important in finding or treating the patient's condition properly.

Our specialty-trained team offers a range of diagnostic and therapeutic procedures, including:

  • Abscess drainage
  • Angiography of all vascular anatomy except cardiac
  • Angioplasty
  • Biliary Drainage and Cholangiograms
  • Biopsy Procedures
  • Embolization
  • Percutaneous nephrostomy
  • Stent Insertion
  • Thrombectomy
  • Thrombolysis
  • Transjugular Intrahepatic Portosystemic Shunts (TIPS)
  • Vascular Interventional procedures

Preparing for Your Procedure

  • Pre-op appointment: This appointment is scheduled prior to the procedure to prepare and educate the patient for the test, answer any questions, and ensure all pertinent information has been completed prior to the procedure to avoid delays on the day of the test. You will be expected to bring with you a patient history form filled out by your doctor to identify any laboratory tests you may need due to ongoing medication regimens, or any history of allergies which may require special attention before your test.
  • Transportation: Patients will need to arrange for someone to drive them home after the test is completed.
  • Food and Drink: Patients may be asked to restrict or inject minimal liquids prior to the procedure. Check with your doctor for details.
  • Medications: Please consult with your physician if you should hold off taking any of your medications before taking this test.
  • Check-in Time: Please arrive 15 minutes prior to your scheduled appointment.

What to Expect During the Procedure

The length of your test will vary depending on what the doctor has ordered. Please expect the procedure to take 1 to 2 hours, and allow an additional 4 to 6 hours for recovery. We encourage patients to use the restroom before the test begins.

During the procedure, you will be asked to lay on a cushioned table in a room with specialized X-ray equipment.

An IV (intravenous) line will be started so that medications can be given during the test, and a skilled radiologist will use a catheter (thin, hollow tube) to inject contrast material into a blood vessel. When the contrast is injected, you may feel a rush of heat throughout the body for about 30 seconds. This is normal. Some patients may also experience temporary nausea.

Once the radiologist has guided the catheter into position, images will be taken so the radiologist can determine if there are any blockages of the arteries. It is important to lay still to ensure clear images are taken.

After the test is complete, you will be moved to a recovery area where you will be asked to lie flat and keep your leg straight for 4-6 hours after the test.

Queen’s will provide your test results to your doctor. Please make a follow-up appointment with your physician to discuss your results.
