[[File:Renal artery angiography.ogg|thumb|right|Renal artery angiography video]]
The technique was first developed in 1927 by the [[Portugal|Portuguese]] physician and neurologist [[Egas Moniz]] at the [[University of Lisbon]] to provide contrasted X-ray [[cerebral angiography]] in order to diagnose several kinds of nervous diseases, such as tumors, artery disease and [[arteriovenous malformations]]. Moniz is recognized as the pioneer in this field.<ref name="pmid11619209">{{cite journal | vauthors = Berrios GE | title = The origins of psychosurgery: Shaw, Burckhardt and Moniz | journal = History of Psychiatry | volume = 8 | issue = 29 pt 1 | pages = 61–81 | date = March 1997 | pmid = 11619209 | doi = 10.1177/0957154X9700802905 | s2cid = 22225524 }}</ref> He performed the first cerebral angiogram in Lisbon in 1927, and [[Reynaldo dos Santos]] performed the first aortogram in the same city in 1929. In fact, many current angiography techniques were developed by the Portuguese at the University of Lisbon. For example, in 1932, [[Fausto Lopo de Carvalho|Lopo de Carvalho]] performed the first pulmonary angiogram via venous puncture of the superior member. In 1948 the first cavogram was performed by [[Sousa Pereira]]. With the introduction of the [[Seldinger technique]] in 1953, the procedure became markedly safer as no sharp introductory devices needed to remain inside the vascular lumen. Radial access technique for angiography can be traced back to

===OCT angiography===
[[Optical coherence tomography]] (OCT) is a technology using [[near-infrared]] light to image the eye, in particular penetrate the retina to view the micro-structure behind the retinal surface.

===Post mortem CT angiography===
Post mortem CT angiography for medicolegal cases is a method initially developed by
While oily solutions<ref name="p17056884"/> require special deposition equipment to collect waste water, watery<ref name="p18430859"/> solutions seem to be regarded as less problematic. Watery solutions also were documented to enhance post mortem CT tissue differentiation whereas oily solutions were not. Conversely, oily solutions seem to only minimally disturb ensuing toxicological analysis, while watery solutions may significantly impede toxicological analysis, thus requiring blood sample preservation before post mortem CT angiography.<ref name="p22704555">{{cite journal |vauthors =Rutty GN, Smith P, Visser T, Barber J, Amorosa J, Morgan B|title=The effect on toxicology, biochemistry and immunology investigations by the use of targeted post-mortem computed tomography angiography|journal=Forensic Sci.

==Complications==
Angiography is a relatively safe procedure. But it does have some minor and very few major complications. After an angiogram, a sudden shock can cause a little pain at the surgery area, but heart attacks and strokes usually
