What it means
CT angiography uses a CT scanner and an intravenous contrast dye to produce detailed images of blood vessels and evaluate for blockages, aneurysms, or structural problems. The dye is injected through a vein in your arm, and images are captured as it flows through your vessels. You will lie on a table that slides through the scanner while the machine rotates around you taking rapid images. The scan is fast, usually five to fifteen minutes. You may feel a warm flush when the contrast is injected. Kidney function is checked before the test because the contrast dye is filtered through the kidneys. You should fast for several hours beforehand. CTA is commonly used to evaluate coronary arteries, pulmonary vessels, and the aorta.
