'''Angiography''' or '''arteriography''' is a [[medical imaging]] technique used to visualize the inside, or [[lumen (anatomy)|lumen]], of blood vessels and organs of the body, with particular interest in the [[artery|arteries]], [[vein]]s, and the [[Heart#Chambers|heart chambers]]. Modern angiography is performed by injecting a radio-opaque [[radiocontrast|contrast agent]] into the blood vessel and imaging using [[X-ray]] based techniques such as [[fluoroscopy]]. With time-of-flight (TOF) magnetic resonance it is no longer necessary to use a contrast.

The word itself comes from the [[Ancient Greek|Greek]] words ἀνγεῖον ''angeion'' 'vessel' and γράφειν ''graphein'' 'to write, record'. The film or image of the [[blood vessel]]s is called an ''angiograph'', or more commonly an ''angiogram''. Though the word can describe both an '''arteriogram''' and a '''venogram''', in everyday usage the terms angiogram and arteriogram are often used synonymously, whereas the term venogram is used more precisely.<ref>{{cite news|title=Arteriograms, Venograms Are Angiogram Territory|url=https://www.chicagotribune.com/1986/01/23/arteriograms-venograms-are-angiogram-territory/|access-date=12 September 2011|author =G.

The term angiography has been applied to [[radionuclide angiography]] and newer vascular imaging techniques such as [[Carbon Dioxide Angiography|CO<sub>2</sub> angiography]], [[Computed tomography angiography|CT angiography]] and [[Magnetic resonance angiography|MR angiography]].<ref>{{cite book|last1=Martin|first1=Elizabeth|title=Concise Medical Dictionary|publisher=Oxford University Press|location=Oxford|isbn=9780199687817|edition=9th|chapter-url=http://www.oxfordreference.com/view/10.1093/acref/9780199687817.001.0001/acref-9780199687817-e-457|chapter=Angiography|doi=10.1093/acref/9780199687817.001.0001|year=2015}}</ref> The term ''isotope angiography'' has also been used, although this more correctly is referred to as [[isotope perfusion scanning]].
