CT Angiography

Before the Appointment 

A booking is required for most CT Angiography Scans. The locations of our CT scanners are listed on your Capital Radiology referral form or you can click Locations and find your most convenient Capital Radiology site to you. Capital Radiology accepts all radiology provider referral forms. So even if you have another form we will happily perform your test.

Some scans require no preparation. Others may require you fast for several hours, or to drink a special contrast medium prior to the examination. When making your booking Capital Radiology staff will advise you of any preparation that may be required.

When you arrive at our clinic you will be greeted by our friendly reception team then escorted to the CT scanning room by our Radiographer. Depending upon the type of procedure you may be asked to change into a medical gown.

In some cases a contrast injection may improve the accuracy of the scan. If contrast is required the injection is usually made into an arm vein. As metal objects can interfere with the x-rays you may be asked to remove metal objects such as glasses, necklaces earings etc.

We request that you complete a questionnaire and sign a consent form before we perform a CT.

On the Day

Please do not eat food for four hours prior to your appointment, but keep well hydrated by drinking fluids. You should wear comfortable, loose-fitting clothing for your CT. You may be asked to change into a gown before your scan. Metal objects, such as jewellery, piercings, eyeglasses, dentures, hearing aids and hairpins, may affect the CT images, so you will be asked to remove such items if possible. Women will be asked to remove bras containing metal underwire. If you have a pacemaker, please advise a staff member before your scan.


CT angiography is used to examine blood vessels in key areas of the body, including the brain, kidneys, pelvis, legs, lungs, heart, neck and abdomen.
