A virtual colonoscopy, also called CT colonography, is a special type of computed tomography scan that is offered as an alternative to a conventional colonoscopy.

It differs in a few ways, however, including how it is performed: A virtual colonoscopy uses a series of Xrays to create a 3dimensional image of the inside of the colon, rather than requiring the insertion of a scope through the rectum and colon (large intestine). Differences between virtual and conventional colonoscopy include: VC can view the colon from many different angles. This is not as easy with regular colonoscopy. VC does not require sedation. You can usually go back to your normal activities right away after the test. Regular colonoscopy uses sedation and often the loss of a work day. VC using CT scan
