CT Virtual Colonoscopy

Virtual colonoscopy is a new non-invasive method that allows radiologists to view the entire colon and see any development of Polyps or Cancer. It is done using high-speed multidetector CT scanner and specialized software, through which images are obtained to view the colon. This scan generates both 2D and 3D images along with the endoscopic views of the colon which are similar to the conventional Colonoscopy.

What is the difference between CT Virtual Colonoscopy and Conventional Colonoscopy?

• Sedation: Virtual Colonoscopy does not require sedation. Conventional Colonoscopy requires sedation.
• Radiations: Virtual Colonoscopy involves radiations. Conventional Colonoscopy does not.
• Tears: Virtual Colonoscopy is minimally invasive and has almost no risk of tears. Conventional colonoscopy has a small risk for colon perforation.
• Imaging: Virtual Colonoscopy can provide images from all angles and can also view outside of the colon. Conventional Colonoscopy can only provide from some angles and can only see inside the colon.
• Duration: Virtual Colonoscopy takes minutes and patients can resume work immediately. Conventional Colonoscopy takes more time and may need one day in the clinic.
