Angiography is a medical procedure that involves the use of X-rays to examine the blood vessels in the body. This procedure is used to diagnose various medical conditions and to evaluate the effectiveness of treatments for these conditions. In this article, we will explore the meaning and definition of angiography, its origin, associations, synonyms, antonyms, and the same root words.
Definitions
Angiography is a medical imaging technique that involves the injection of a contrast agent into the blood vessels to make them visible on X-ray images. This procedure is used to diagnose and treat a variety of medical conditions, including heart disease, stroke, and cancer.
Origin
The word angiography comes from the Greek words “angeion” meaning vessel and “graphien” meaning to write. The first angiogram was performed in 1927 by Portuguese physician Egas Moniz, who used a contrast agent to visualize the blood vessels in the brain.
Meaning in different dictionaries
According to the Merriam-Webster dictionary, angiography is defined as “the radiographic visualization of the blood vessels after injection of a radiopaque substance.” The Oxford English Dictionary defines angiography as “a medical procedure in which a contrast medium is injected into the bloodstream to visualize the blood vessels.”
Associations
Angiography is often associated with other medical procedures, such as angioplasty and stenting. Angioplasty is a procedure that involves the use of a balloon catheter to open a blocked blood vessel, while stenting involves the insertion of a small metal mesh tube to keep the vessel open.
Synonyms
Some synonyms of angiography include arteriography, venography, and vascular imaging.
Antonyms
There are no antonyms for angiography.
The same root words
Some words that share the same root words as angiography include angiology (the study of blood vessels), angiotensin (a hormone that regulates blood pressure), and angiogenesis (the formation of new blood vessels).
