Virtual Colonoscopy Screening is a Safe, Minimally-Invasive Procedure for Colon Cancer Detection
At Winchester Imaging, we offer CT Virtual Colonoscopy (also called CT Colonography) as a safe, minimally invasive way to screen for colon polyps and colorectal cancer.
Virtual colonoscopy (colonoscopia virtual) is a non-invasive alternative to conventional colonoscopy.
Unlike traditional colonoscopy, which requires the introduction of a long tube into the rectum, virtual colonoscopy uses CT imaging to provide a comprehensive view of the colon.
How Does a Virtual Colonoscopy Work?
A virtual colonoscopy, or CT colonography, involves a quick and painless CT scan. The procedure typically takes about 15 minutes. During the scan, the patient lies on a table while the CT scanner takes detailed images of the colon. These images help detect polyps, cancer, and other abnormalities.
Who Should Have a Virtual Colonoscopy?
According to guidelines endorsed by the American Cancer Society and other national groups, colorectal cancer screening is recommended for individuals beginning at age 50. For those at high risk, screening should start at age 40. High-risk individuals include those with a family history of colorectal cancer, a personal history of inflammatory bowel disease, or other risk factors.
Advantages of Virtual Colonoscopy

Before Your Exam
To ensure the clearest images possible, your bowel, must be fully cleared.
- You’ll follow a special clear-liquid diet the day before your exam.
- You’ll take a prescribed bowel preparation solution.
- You will drink a small amount of contrast liquid to help distinguish any remaining stool in the colon.
Our team at Winchester Imaging will provide simple, step-by-step instructions and will be available to answer questions
During Your Exam
- A small, flexible tube is gently placed just inside the rectum.
- The colon is carefully filled with carbon dioxide to distend it and improve visualization. This gas is safely absorbed by the body or breathed out.
- You may feel temporary fullness or mild cramping.
- The CT scanner takes images while you briefly hold your breath.
- Images are obtained while you are lying on your back, stomach, and side.
No sedation is required, so you can return to your normal activities right away.
After Your Exam
- No need for a driver.
- Most patients feel well enough to resume normal activities.
- You may experience mild bloating for a short time, which typically resolves quickly.
- A board-certified radiologist will review your images, and your results will be sent promptly to your referring provider.
