Computed tomography angiography (CTA) is an imaging technique that uses X-rays to create detailed images of the blood vessels. An iodine-containing contrast agent is injected intravenously to make the vessels clearly visible. CTA allows for the diagnosis and assessment of vascular diseases such as aneurysms, stenoses, and thrombosis. It offers fast and precise visualization of the arteries and veins throughout the body.

Computed tomography angiography (CTA) is an imaging technique that uses X-rays and an iodine-containing contrast agent to create detailed images of the blood vessels. It is used to diagnose and assess vascular diseases.
During a CTA, an iodine-containing contrast agent is injected intravenously to make the blood vessels visible. The patient then lies on an examination table that moves through a CT scanner. This scanner takes rapid X-ray images from different angles to create detailed 3D images of the vessels.
A CTA is performed to diagnose and evaluate vascular diseases such as aneurysms, stenoses (narrowings), and thrombosis (blood clots). It offers fast and precise visualization of the arteries and veins, which is helpful in planning treatment strategies.
The CTA is usually not painful. The contrast agent injection may cause a brief feeling of warmth, but the actual examination is painless. Some patients may find lying on the examination table uncomfortable, but the procedure only takes a few minutes.
As with all imaging procedures using X-rays, there is a small amount of radiation exposure with CTA. The iodine-containing contrast agent can cause allergic reactions in rare cases. It is important to inform the doctor about any existing allergies, kidney problems, or pregnancy to minimize potential risks.
