Current technology and clinical applications of three-dimensional angiography.

Three-dimensional (3D) angiography was first proposed by Cornelius and advanced into clinical practice by Voigt in 1975. Since then, a variety of improvements have been developed as a result of the increased speed and data transfer afforded by modern computers. Recent publications by Fahrig and others have brought 3D angiographic imaging to the forefront. The 3D evaluation of cerebral aneurysms and arteriovenous malformations no longer is a clinical curiosity, but an absolute necessity.
