An angiogram image is a type of medical imaging that uses X-rays to create an image of the blood vessels in the body. It is used to diagnose and treat conditions such as blockages, narrowing, or aneurysms. The term 'aortas' refers to the largest artery in the body, which carries oxygenated blood from the heart to the rest of the body. An angiogram image of the aortas can be used to detect any abnormalities in the artery.
