Virtual Colonoscopy

A virtual colonoscopy is often referred to as a CT colonoscopy, CT scan colonoscopy, or CT virtual colonoscopy and involves evaluating the health of your colon to screen for any potential health risks. Virtual colonoscopies may be needed if you are fifty years or older or if you have blood in your stool, a family history of colon cancer, or have had colon polyps. At Park Avenue Radiologists, we are dedicated to providing you the most minimally invasive, accurate medical imaging currently available.

What is a virtual colonoscopy?

A virtual colonoscopy is a noninvasive colonoscopy that uses images of the colon to detect any irregularities or signs of a disease or medical condition. Traditional colonoscopies involve inserting a tubular camera through the rectum to gather images of the colon. With advancements in radiology, a virtual colonoscopy does not require sedation and is less invasive than traditional colonoscopies.

What can a CT colonoscopy help diagnose?

Virtual colonoscopies may be used to monitor the growth of polyps or cancerous tumors within the colon. Additionally, a CT colonoscopy may be used to monitor the progress of a colon cancer treatment or surgery and to see if any growths return. A CT scan colonoscopy may also be ordered after other abnormal test results or if you display symptoms of Crohn’s disease. In some minor cases, a CT virtual colonoscopy can help determine the cause of diarrhea, such as inflammatory bowel disease or irritable bowel disease.

What can I expect from a CT scan colonoscopy?

During a CT virtual colonoscopy, a small tube will be inserted one to two inches into the rectum. This tube will gently inflate your colon with air; this is done to reduce any folds or creases in your colon that may conceal polyps or tumors. Once this is done, the procedure table will begin to pass through the CT scan machine. You may be asked to hold your breath for a few seconds during your CT virtual colonoscopy. One of our radiologists may also ask you to reposition and pass through the CAT scan machine again for additional images.

How long does a colonoscopy take, & when will I get my results?

A virtual colonoscopy can be completed in approximately fifteen minutes. If any images are unclear, you may need to pass through the CAT scan machine for additional scans. Our radiologists will begin to analyze your virtual colonoscopy results as quickly as possible and notify your doctor or healthcare provider immediately when your results are available.
