"aortography" 的定义和意义

What is "aortography"?

Aortography is a medical imaging procedure used to examine the aorta, which is the large artery that carries blood from the heart to the rest of the body. During this procedure, a special dye is injected into the blood vessels, usually through a thin tube called catheter, to make the aorta and its branches visible on X-ray images. This helps doctors see and diagnose problems such as blockages, aneurysms, or other abnormalities in the aorta. The images produced can help with treatment decisions or planning surgeries.
