CT angiography (CTA) is a CT scan of your blood vessels with contrast dye. The dye contains iodine. A nurse injects it into a vein, and within seconds the scanner records how it fills your arteries. The software then turns hundreds of thin slices into a 3D map of the vessels. It shows narrowing, plaque, aneurysms, blockages and detours the blood has found around them. No catheter goes into an artery. At Oberig Clinic the scan is done in the Diagnostic Department on Siemens Somatom scanners, and radiologists write the report.
CTA of the brain vessels
This is the most common request. A neurologist or neurosurgeon orders it for a suspected aneurysm, after a stroke or a mini-stroke (TIA), for a severe headache with no clear cause, for fainting, or before vessel surgery. The images show the arteries at the base of the brain (the circle of Willis), narrowed segments, malformations and clots. Often the carotid and vertebral arteries in the neck matter too. Then the radiologist scans the head and neck in one go, from the aortic arch to the top of the skull. A plaque in the carotid artery causes strokes more often than changes inside the brain itself. A neck-only CTA makes sense when an ultrasound has found a narrowing or your doctor hears a bruit over the artery. To see how well blood reaches the brain tissue, the team adds a perfusion scan.
Heart and coronary arteries
Coronary CTA shows plaque and narrowing in the arteries that feed the heart muscle. Your cardiologist orders it when chest pain does not look like typical angina, when a stress test gives an unclear answer, or to rule out coronary disease before surgery. A clean coronary CTA almost rules out a significant blockage. The heart must beat slowly and evenly for sharp images, at about 60-65 beats a minute. Sometimes the doctor gives you a pill to slow it down. The same scan checks bypass grafts after heart surgery and rare inborn variants of the coronary arteries.
Leg arteries, lungs and other areas
Leg CTA helps when your calves hurt as you walk and the pain fades once you stop (intermittent claudication). Cold feet and slow-healing wounds in diabetes are other reasons. The surgeon gets a map of the arteries from the aorta down to the toes and plans a stent or a bypass. The same method covers the aorta, the kidney arteries and the arm vessels. A suspected clot in the lungs (pulmonary embolism) calls for a CTA of the pulmonary arteries. That is an emergency.
How to prepare and what happens
Every CTA uses contrast dye. Safety of the dye comes first. Here is the order:
- a few days before, get a blood creatinine test if you are over 65, have diabetes or kidney disease: it gives your kidney filtration rate (eGFR), and below 30 ml/min the dye is not used,
- if you take metformin for diabetes, your doctor may ask you to stop it 48 hours before and after the scan,
- if you have ever reacted to contrast dye, book a visit with the anaesthetist in advance for special preparation,
- do not eat for 4 hours before the scan, water is fine, bring your old reports and discs,
- in the CT room a nurse places a small cannula in the vein at your elbow, you lie on the table, a pump injects the dye, and the scan itself takes a few seconds.
As the dye goes in, you feel a wave of warmth. It is normal and passes in a minute. The whole visit takes 15-30 minutes. Afterwards you stay at the clinic for up to 30 minutes under observation. Drink plenty of water to help your kidneys clear the dye. If you breastfeed, take a 24-hour break.
Common questions
How is it different from a standard angiogram?
A standard angiogram uses a catheter. The doctor threads it in through an artery in your groin or wrist. It is done when treatment is planned during the same procedure. CTA needs no artery puncture. For diagnosis, it comes first.
Can I have it during pregnancy?
No, only when your life depends on it. Tell the doctor if there is any chance you are pregnant.
When will I get the results?
You get the radiologist's report and a disc with images within 24 hours, except weekends and public holidays. The doctor who referred you will explain it. You can also see a neurologist or a cardiologist at the clinic.
