Computed tomography angiography (also called CT angiography or CTA) is a computed tomography technique used for angiography—the visualization of arteries and veins—throughout the human body. Using contrast injected into the blood vessels, images are created to look for blockages, aneurysms (dilations of walls), dissections (tearing of walls ...
Coronary CT angiography (CTA or CCTA) is the use of computed tomography (CT) angiography to assess the coronary arteries of the heart.The patient receives an intravenous injection of radiocontrast and then the heart is scanned using a high speed CT scanner, allowing physicians to assess the extent of occlusion in the coronary arteries, usually in order to diagnose coronary artery disease.

Cross-sectional computed tomography angiogram of RCA (between aorta and pulmonary artery) at the worst intramural site of compression (right anterior oblique projection). Black arrow = compressed intramural RCA. Intravascular ultrasound imaging of intramural RCA during systole (left) and diastole (right) in a patient with mild symptoms.
Computed tomography angiography (CTA), an imaging methodology using a ring-shaped machine with an X-ray source spinning around the circular path so as to bathe the inner circle with a uniform and known X-ray density. Cardiology uses are growing with the incredible developments in CT technology.
FIGURE 3. Axial (left) and coronal (right) CT angiography images of the abdominal aorta evaluating for aortic aneurysm. [citation needed] CT angiography (CTA) is highly effective for evaluation of the arterial system, and has largely replaced conventional angiography due to the lower risk profile and ability to survey the entire abdomen.
Magnetic Resonance Imaging (MRI): MRI or MR angiography can similarly detail the vascular anatomy and is often used in children to reduce radiation exposure. Barium Swallow Study: If there are symptoms like dysphagia, this test can reveal if the esophagus is compressed by the aberrant artery, suggesting the presence of a vascular ring.
