Angiography or arteriography is a medical imaging technique used to visualize the inside, or lumen, ... Moniz is recognized as the pioneer in this field. [3]
Cerebral angiography was first described by Egas Moniz, a Portuguese physician and politician, in 1927. He performed this procedure on six patients. He performed this procedure on six patients.

Over the course of a year, Egas Moniz, the inventor of cerebral angiography, ran experiments with various dye solution percentages that were injected into arteries to help better visualize the blood vessels in the brain before discovering that a solution consisting of 25% sodium iodide was the safest for patients, as well as the most effective ...
Selective pulmonary angiogram revealing significant thrombus (labelled A) causing a central obstruction in the left main pulmonary artery. Pulmonary angiography (or pulmonary arteriography,conventional pulmonary angiography, selective pulmonary angiography) is a medical fluoroscopic procedure used to visualize the pulmonary arteries and much less frequently, the pulmonary veins.
In 1927, Egas Moniz introduced cerebral angiography, whereby both normal and abnormal blood vessels in and around the brain could be visualized with great precision. In the early 1970s, Allan McLeod Cormack and Godfrey Newbold Hounsfield introduced computerized axial tomography (CAT or CT scanning), and ever more detailed anatomic images of the ...
