Computed Tomography (CT) Angiography
CT angiography or CTA combines conventional CT scan technology with traditional angiography to create high-detail images of blood vessels. CT is a non-invasive medical test that helps doctors diagnose and treat medical conditions. CT combines x-rays, an array of detectors that rotate around the body, and sophisticated computers to produce detailed cross-sectional images.
Angiography uses an injection of contrast media into a large blood vessel, usually in the groin, to visualise blood vessels and blood flow. When the contrast media is injected into a vein the study is called a venogram and when injected into an artery the study is called an arteriogram. A doctor might order CT angiography to see if a patient has any narrowing or blockage of the arteries, an aneurysm, deep vein thrombosis, pulmonary embolism or any other vascular problem.
CT examinations are performed at the following South Coast Radiology locations:
- John Flynn Hospital
- Pindara Private Hospital
- Palm Beach
- Runaway Bay
- The Women’s Imaging Centre, Southport
- Tweed Heads
- Varsity Lakes
Patients having CT angiography need an injection of contrast media (or dye), through a vein or artery. The contrast media is opaque on x-rays and so the vessel is made visible. However, some people might be allergic to the contrast media.
Please note on the request form if a patient:
- Has asthma
- Is allergic to seafood of shellfish
- Has had a previous allergic reaction to contrast media
- Is taking medication for Type 2 Diabetes
During CT Angiography
CT scans are generally painless, relatively fast and straightforward. The examination time varies, but averages around 30 minutes. Recent technology advancements now enable multi-slice CT scanners to obtain multiple cross-sectional slices during a single rotation. The resultant thinner slices show better detail and take less time.
All South Coast Radiology radiographers have the necessary qualifications and experience to ensure the best patient care and high-quality x-rays. All of our radiographers are accredited and licensed by Queensland Health and the Australian Institute of Radiography.
After CT angiography
One of our radiologists will interpret the CT angiogram and provide a comprehensive report about the findings. We will advise the patient to return to their doctor to discuss angiography results.
Processing and reporting of images could take up to two hours. If you are a registered a referrer you can access your patient’s digital x-rays, scans and reports through our secure online archival system, or view the films we provide. For more information about registering to access patient images visit the Access Medinexus Portal section. <3.1 for referrers>
Any hardcopy images and report can generally be delivered to the referrer, by lunchtime on the next working day. If the patient needs to be reviewed on the day of the scan, the patient can wait for the CT images and we will fax or email the results to the referring doctor.
