Lower Extremity Angiogram
Detects atherosclerotic disease that has narrowed the arteries to the legs.

Renal Angiogram
Visualize blood flow in the renal arteries, those supplying the kidneys, in patients with hypertension and those suspected of having kidney disorders. Narrowing (stenosis) of a renal artery is a cause of high blood pressure in some patients, and can be corrected surgically. A special computerized method of viewing makes CT renal angiography a very accurate examination. It is also done in prospective kidney donors.

Brain Angiogram
Identify atherosclerotic disease, aneurysm, or dissection in the body's main artery, the aorta and its major branches, the iliac arteries. Able to detect the presence of aneurysms and their feeding vessels. The information received is critical in determining the correct management (i.e. embolization, surgery, etc.) for patients. With higher resolution and faster scan times, even smaller aneurysms will now be detectable.

Carotid Angiogram
CTA also is used to detect narrowing or obstruction of arteries in the pelvis and in the carotid arteries bringing blood from the heart to the brain. When a stent has been placed to restore blood flow in a diseased artery, CT angiography will show whether it is serving its purpose. Examining arteries in the brain may help reach a correct diagnosis in patients who complain of headaches, dizziness, ringing in the ears, or fainting. Injured patients may benefit from CTA if there is a possibility that one or more arteries have been damaged. In patients with a tumor, it may be helpful for the surgeon to know the details of arteries feeding the growth.
