The term virtual colonoscopy was initially coined by researcher D.J. Vinig in 1994 who demonstrated the feasibility of creating three dimensional pictures of the colon using spiral computed tomography (CT) technology. Since the term virtual colonoscopy is misleading and implies a colonoscopic procedure rather than generation of images, this methodology should be referred to as virtual colonography (VC). VC can be performed using CT or magnetic resonance imaging (MRI). In the December 2003 issue of the journal "Gut," researcher Ajaj W. and colleagues present an evaluation of a new MR colonography technique employing a water enema for contrasting and extending the colon.
