Angiocardiography

…Angiography is performed to diagnose diseases of the blood vessels themselves, such as arteriosclerotic blockages, aneurysms, varicose veins, thrombosis, congenital malformations, and trauma, as well as to diagnose benign and malignant tumors in solid organs such as the brain, liver, and kidneys by imaging the blood vessels that control these organs. When it is performed to diagnose cardiac lesions, it is sometimes called angiocardiography or coronary angiography, which is sometimes distinguished from other general angiography, but the method is basically the same. The contrast agent currently used in angiography is a triiodine compound, which has three iodine atoms bonded to a benzene nucleus. When X-rays are taken with this in the blood vessels, the iodine atoms absorb X-rays so much that only the blood vessels are depicted as standing out from the other body tissues that do not contain the contrast agent. …
