Cerebral angiography was pioneered by the Portuguese neurologist Egas Moniz in 1927 and has since continued to evolve to be the essential imaging for cerebrovascular pathology, frequently yielding more telling diagnostic images than conventional MRI or CT scans. With the expansion of endovascular techniques cerebral angiography has further allowed for immediate intervention with embolization, coiling and even clot retrieval.

It also produces some incredible images of the cerebral circulation!
