Computed tomography arteriography and venography are minimally invasive image techniques using a scanner that releases X-rays, which create detailed images of the blood vessels and veins. These images are used in diagnosing conditions such as peripheral vascular disease, aneurysms and abdominal pain. 

How to Prepare for a CTA/CTV Scan

  • Your interventional radiologist will inform you if contrast dye will be used. If so, you should not eat or drink 4-6 hours before the scan.
  • If you have any allergies, are taking medication, blood thinners, have kidney problems, or are pregnant please notify the staff.
  • Remove any jewelry and metal accessories.
  • Your registered radiology technologist will help position you onto the padded radiographic table, where you will be lying on your back during the scan. You may have pillows or straps to help keep you in position.
  • If you are uncomfortable, you can ask for a blanket or pillow. Those with anxiety may also ask for headphones, which play music during the scan.
  • If the scan requires contrast dye, this is injected through an IV into your veins. You may feel a warm sensation, but should not feel pain.

What to Expect

  • Scanning takes 2 minutes.
  • The table will move you through the CT scanner, which is a large, tunnel-shaped machine, and back out. You may go through more than once to make sure the images have captured the correct details.
  • You may be asked to hold your breath as you go through the scanner to make sure your body is as still as possible.
  • The technologist will be in an attached room, monitoring the progress of the scan. He/she will be able to communicate with you via microphone.

What to Expect after a CTA/CTV Scan

  • Once it is confirmed that the scan was successful, you can leave and return to normal activity.
  • Your interventional radiologist will analyze the images, and discuss them with your primary care or referring physician, who will consult with you about the next steps in your treatment process.
