What should a CT angiography report of the aorta include?

• A. Aortic diameter measurements, presence or absence of dissection or aneurysm, intramural hematoma, involvement of branch vessels, and related complications
• B. Only heart chamber analysis
• C. Only evaluation of lung parenchyma
• D. Description of abdominal aorta only

Answer: (A)

The main idea here is to describe the aorta comprehensively on CT angiography, not just isolated parts. A CTA report of the aorta should document the entire aorta from thoracic through abdominal segments, including precise diameter measurements at standard locations, the presence or absence of acute or chronic aortic disease, and the specific pathology seen—such as dissection with its true and false lumens, aneurysm, intramural hematoma, or other aortic ulcers. It should also note whether branch vessels arising from the aorta are involved or compromised (for example, renal, mesenteric, supraceliac, or iliac branches) and any related complications like malperfusion, rupture, or downstream ischemia. This information is essential for diagnosis, risk stratification, and treatment decisions, including endovascular or surgical planning. Focusing only on heart chambers or only on lung parenchyma misses the primary purpose of the exam, which is to evaluate the aorta itself and its branches for clinically important pathologies. Describing just the abdominal aorta, for instance, would neglect potential disease in the thoracic aorta or missed involvement of branch vessels and complications that could change management.
