CT Angiogram of Thoracic Aorta

A CT Angiogram of the Thoracic Aorta is a diagnostic medical test that combines a CT scan with an injection of a contrast material to produce pictures of the thoracic aorta and its branches. The thoracic aorta is the largest artery in the chest and it carries oxygenated blood from the heart to the rest of the body.

This procedure helps to visualize and evaluate the thoracic aorta for aneurysms, dissections, or other pathologies. It is particularly helpful in assessing aortic aneurysms and planning for surgical or endovascular intervention. The procedure also provides information about the size, shape, and condition of the thoracic aorta and can detect inflammation or other changes in its walls.The CT Angiogram of Thoracic Aorta is often recommended to monitor patients with known aortic disease, those who have family history of aortic disease, and patients with certain genetic disorders that affect the connective tissue and can lead to aneurysms.

• Fasting : In most cases, patients are advised to fast for several hours before the test, usually overnight.
• Allergies : It is crucial to inform your doctor about any allergies, especially to contrast materials or iodine. An allergic reaction to the contrast material can cause itching, a rash, or more serious reactions.
• Medications : Inform your doctor of all medications you are taking, as certain medications may need to be stopped before the procedure.
• Hydration : It is usually advised to drink plenty of water the day before the test to help clear the contrast material from your body after the test.
• Pregnancy : If you are pregnant or suspect you might be, you must inform your doctor. Although the radiation exposure from this test is minimal, any radiation exposure during pregnancy should be avoided if possible.
• Kidney function : If you have known issues with your kidneys, let your doctor know. The contrast material could potentially harm your kidneys, especially if their function is already compromised.
