What is this test?
CT angiography, or CTA, is an imaging test that uses X-rays and an injected iodine-containing contrast material. It can show the blood vessels, organs, and surrounding tissues in the abdomen and pelvis.
Why might I need this test?
Your clinician may order this test to investigate symptoms such as sudden leg pain or swelling, unexplained bleeding, severe abdominal or pelvic pain, or signs of reduced blood flow. It may also be used to evaluate blood vessels before a procedure or to monitor certain conditions.
How is the test performed?
You lie on a CT table while the scanner takes X-ray images from different angles. Contrast material is usually injected through a vein in your arm, and the scan is completed quickly. You may be asked to hold your breath briefly during parts of the examination.
How do I prepare for the test?
Follow the instructions provided by your healthcare professional. You may need to avoid eating or drinking for a short period, although fasting is not required for every CTA. Tell the imaging team about kidney disease, prior contrast reactions, iodine allergy, pregnancy or breastfeeding, and any medications you take.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Abnormal findings may indicate a narrowed or blocked blood vessel, an aneurysm, abnormal bleeding, or an injury involving an abdominal or pelvic organ. The scan can also reveal conditions affecting nearby organs or tissues. Your clinician will interpret the images in the context of your symptoms, examination, and other tests.
Short name
