Abstract :
Virtual Colonoscopy (VC) is a medical imaging procedure which combines the use of series of images, produced from multislice CT or MRI, and high-power computer to reconstruct 2D and 3D images of the colon, from rectum to ileocecal valve. With the appropriate workstation and software programs, these images are displayed dynamically, allowing radiologists to conduct virtual examination of the entire colon, simulating the way endoscopists view the colon. At current time, VC using multislice CT is used more widespread than MRI and this technique is also called CT colonography (CTC). In this article, virtual colono-scopy based upon multislice CT will be discussed and the term CT colonograpy (CTC) will be applied interchangeably with virtual colonoscopy (VC).
