Understanding CT Virtual Colonoscopy
A CT Virtual Colonoscopy is a medical imaging procedure that utilises computed tomography (CT) scans to create detailed images of the colon and rectum. This non-invasive test is also known as CT Pneumocolon or CT Colonography and is performed on the abdomen and pelvis region. It is an alternative to traditional colonoscopy, offering a less invasive means of examining the large intestine.
Purpose and Benefits of a CT Virtual Colonoscopy
The primary purpose of a CT Virtual Colonoscopy is to screen for polyps or cancer in the large intestine. It is beneficial for patients who are at risk of colorectal cancer, those who have had an incomplete traditional colonoscopy, or individuals who wish to avoid the invasiveness of a conventional colonoscopy. The benefits of this scan include its non-invasive nature, no need for sedation, and a comprehensive view of the colon that can also detect abnormalities outside the colon.

Further Information on the Service
Scan Procedure
A CT Virtual Colonoscopy involves the use of a CT scanner to take multiple X-ray images of the colon. These images are then processed by a computer to create a detailed, three-dimensional view of the colon's interior.
Preparation for the Scan
Prior to the scan, patients may need to follow a special diet and take a bowel-cleansing agent to empty the colon. Specific instructions will be provided by the imaging center.
What to Expect on the Day
During the procedure, which typically lasts about 10 to 15 minutes, the patient lies on a table that slides into the CT scanner. Air or carbon dioxide is introduced into the colon to expand it for better imaging. Some patients may experience mild discomfort due to the air pressure but generally, there is minimal pain.
After the Scan
Post-scan, patients can usually resume normal activities. Results are typically available within a few days and will be communicated by the referring physician or the imaging center.
Alternative Imaging Options
Other imaging options include traditional colonoscopy, sigmoidoscopy, and barium enema, which may be considered based on symptoms and the consultant's recommendation.
