Angiography

CT Angiograms are a specific type of CT scan that use contrast (x-ray dye) injected at a high rate to evaluate arteries of the body. This CT scanner then uses special software to create realistic 3D images of your arteries and gives the Radiologist interpreting the test the ability to examine your blood vessels in detail.

CT angiograms are typically ordered to look for blockages caused by atherosclerosis (plaque build-up on the inside wall of arteries), dissections (tears of the lining of the artery wall), and aneurysms (abnormal bulges in the artery wall).

Lake Imaging performs CT Angiograms at the following locations:

What to bring

  • A referral from your doctor or specialist is required for this examination, please ensure you bring this to your appointment.
  • Medicare or concession card
  • Previous imaging not performed at Lake Imaging

Preparation

You may have nothing to eat or drink for one (1) hour prior to your examination.

Please inform the staff at the time of making your appointment if you are taking any diabetic medication, have kidney disease or have had a previous reaction to x-ray contrast.

What to expect during my procedure

You will be asked a few safety questions before being asked to lie flat on the CT examination table with your head resting on a special cradle. You will need to keep very still for the duration of the scan, as the table moves through the gantry opening and the image data is acquired. You may hear a humming noise during the scan, but no moving parts will touch you.

An intravenous injection of contrast medium (x-ray dye) will be required. The contrast provides valuable information by the highlighting the blood vessels on the CT images. Prior to the injection of contrast you will be asked to complete a safety questionnaire and provide consent.

During the injection you may notice a sensation of warmth and a metallic taste or smell. These sensations will quickly subside.

The CT scan will take just a few minutes.

Risks and side effects

CT scans involve the use of ionising radiation.  CT scans will only be performed when any potential risks are far outweighed by the benefits to the patient. Lake Imaging’s state of the art CT scanners and staff trained in radiation reduction techniques use the latest in CT dose efficient technology to ensure the minimum dose necessary is used to produce the best quality images for an accurate diagnosis.

If it is possible that you may be pregnant, please inform our radiology team before your examination to avoid any risks to your unborn child.

Contrast injections can make some patients feel nauseous or on rare occasions cause an allergic reaction. 

If you are worried or concerned about having a CT scan you should discuss this with your referring doctor or medical specialist before coming for your examination.

Who will perform and report my examination

At Lake Imaging your CT examination will be performed by a radiographer (or medical imaging technologist), who has a degree in medical imaging. A Radiologist (a doctor specialising in the interpretation of medical images), will prepare and send a report to your referring doctor detailing the findings of your examination.

What to expect after my procedure

You will be free to leave our clinic shortly after your CT scan has been completed. You may, then drive yourself home, eat and drink normally and resume your normal activities.

The contrast administration will be absorbed and passed out of your body in your urine during the next 8 to 10 hours. Drinking plenty of fluid will assist this process.

How do I receive my results?

If your CT results are urgent, or you have an appointment straight after the scan with your doctor or health care provider, Lake Imaging will arrange to have your results available immediately delivered to your referring doctor.

Otherwise your referring doctor or health care provider will receive your report within 48 hours of your examination.

Please ensure that you make a follow up appointment with your referring doctor or health care provider to discuss your results.

Can I bring a relative or friend?

You are welcome to have a friend or relative accompany you for your appointment but for radiation safety reasons, they will only be allowed into the CT room under special circumstances.

Children will not be allowed into the CT room and you will need to make arrangements for their care during your examination.
