CT Angiography

Advances in cross-sectional imaging – CT, MRI and Ultrasound – have provided complementary tools for the non-invasive diagnosis of vascular disease. CT angiography or CTA provides accurate three-dimensional images of virtually any artery in the body. It is a powerful tool for the diagnosis of peripheral vascular disease, occlusive disease of the renal and mesenteric arteries, and aneurysms and occlusive disease of the thoracic and abdominal aorta. CT Angiography (CTA) has become the new “Gold Standard”.

CT Angiography – Aorta
This test is done to look specifically at the aorta. CT images are obtained from the aortic arch through the symphysis. No oral contrast is given. IV contrast is injected through an 18G IV at a rapid rate to get an optimum scan. Total test time is approximately 15 minutes. The test is usually performed to evaluate for arterial blockage, aneurysm, or dissection.

CT Angiography – Head and Neck
This exam is done to see the vessels that run from the neck up through the head. CT images are obtained from the aortic arch up through the head. I.V. contrast is administered to the patient to highlight the vessels. Patients are instructed to remove all metal from the head area including dentures. Total test time is approximately 15 minutes.

CT Angiography – Runoff
This study evaluates the aorta and its branches as it flows down through the body. CT images are obtained from mid-chest down to the feet. I.V. contrast is administered to the patient to highlight the vessels. The patient is instructed to lie very still and not move their legs during the scan. Total test time is approximately 20 minutes. Patients should bring previous films or related exams to their appointment. This information is very important and will expedite the report of the diagnosis back to the referring physician.
