PRP's CT Angiogram Service Information

PRP Diagnostic Imaging provides CT Angiogram (CTA scan) to visualise arteries, detect blockages, and assess blood flow.

Our expert team utilises this advanced imaging technique, which combines a CT scanner with an intravenous injection of contrast media, to create detailed pictures of your blood vessels and surrounding tissues. This allows us to precisely identify abnormalities and understand intricate vascular pathways.

Please advise us beforehand

If you have had an adverse reaction to a previous contrast injection or other drugs or if you have any renal impairment. We will ask you to complete a questionnaire before the examination and sign a consent to the contrast injection if it is required for your examination.

If you are, or may be, pregnant.

Preparation

Fast 2 hours prior to appointment and drink 750ml water 1 hour before appointment.

Special precautions

You may not be able to have the contrast injection if you have had a reaction to a previous injection, or have significant renal failure.

Special instructions for diabetics

If your examination requires fasting, then book an early morning appointment and have your breakfast and diabetic medication after the examination.

If your examination will require an intravenous injection of contrast medium, we need to know your renal function. Please bring along the results of your most recent blood test creatinine level.

What happens during the procedure

For your scan, you may be asked to change in to a gown to ensure no metal on your clothes interferes with the quality of your scan.
Once ready, one of our highly trained technicians will help you onto the CT bed having you laying on your back. They will then insert a cannula into your arm which allows us to administer Iodinated contrast which is essential to highlight the vessels we are aiming to demonstrate for your scan.
You will then be connected to an injector which allows us to give the contrast dye during the scan. The technician will do some planning scans which involve you slowly going in and out of the CT machine. You may be asked to hold your breath several times for approximately 10 seconds during the scan.
Upon injection of the CT dye, you may feel a hot flush, a metallic taste and even feel like you have wet yourself. These are all normal sensations and will pass in about 20-60 seconds. The CT Angiogram itself will take about 5 minutes.
If you have experienced any previous adverse reactions to CT contrast, or have any allergies, please discuss this with our technicians at the time of your scan.
After your scan, we will assist you off the scanner and remove your cannula so you can go home.

How long does it take?

A CT Angiography takes approx 30 minutes to complete.

After your examination

There are no restrictions after having a CT Angiogram, however it is recommended that you have a high fluid intake for 24 hours in order to flush out the contrast from your system.

Your images and report

After your examination, the most pertinent images from your study will be available on the myPRP patient portal. A report, along with the images will be sent directly to your referring doctor. PRP will store digital copies of all studies on our secure database for comparison with any future examinations.

Please bring any previous X-rays with you.

It is important that you return to your doctor with your examination results. Whether they are normal or abnormal, your doctor needs to know promptly so that a management plan can be formulated.

Possible complications

Allergic reactions to contrast material can occur but significant reactions are rare, and generally respond to adrenaline. Our staff members are equipped and trained to treat contrast reactions.
