CT Colonoscopy - Purpose & Procedure

CT Colonoscopy, also known as Virtual Colonoscopy, is a non-invasive diagnostic imaging test used to examine the large intestine (colon and rectum) for polyps, tumors, colorectal cancer, and other abnormalities. It uses advanced CT scan technology to create detailed 2D and 3D images of the colon without the need for traditional invasive colonoscopy.

CT Colonoscopy is widely recommended for early detection of colorectal cancer, especially in patients who are at average to moderate risk or those who cannot undergo conventional colonoscopy.

What is CT Colonoscopy?

CT Colonoscopy is a specialized CT scan that provides high-resolution images of the colon using low-dose radiation. During the scan, air or carbon dioxide is gently introduced into the colon to expand it, allowing clear visualization of the bowel lining.

This test is fast, painless, and usually completed within 10–15 minutes, making it a preferred screening option for many patients.

Why is CT Colonoscopy Done?

CT Colonoscopy is performed to:

• Screen for colorectal cancer

• Detect colon polyps at an early stage

• Evaluate unexplained rectal bleeding

• Investigate chronic constipation or diarrhea

• Assess abdominal pain or bowel habit changes

• Screen patients with a family history of colon cancer

It is especially useful for patients who:

• Cannot tolerate traditional colonoscopy

• Have incomplete colonoscopy results

• Prefer a minimally invasive option

You will be advised to follow a liquid diet and take bowel-cleansing medication a day before the scan to ensure a clear colon.
