Virtual Colonoscopy

What Is A Virtual Colonoscopy?

A virtual colonoscopy is a CT scan of your abdomen after the colon has been gently filled with air. The scan is then sent to a computer workstation where the data is analyzed. The exam takes only about 15 minutes to perform, eliminates any risk of colon perforation, and the patient does not need to be sedated.

In addition, this process allows the performing physician to see other abdominal organs, resulting in early diagnosis of kidney cancers, liver cancers, kidney stones, and other diseases.

While CT colonography is an evolving technology, recently published studies with modern multi-slice equipment such as that utilized at South Jersey Radiology Associates (SJRA) show detection rates (sensitivity) of 90-95% for polyps greater than 1 cm in size, in essence, as effective as traditional, invasive colonoscopies.

What Can A Virtual Colonoscopy Detect?

A virtual colonoscopy is a minimally invasive study that couples X-ray technology and CT scan technology together to investigate gastric areas of the human body. A virtual colonoscopy is useful in diagnosing ulcers, polyps, and infections. A virtual colonoscopy can be used as a screening study for various types of cancers including colon cancer, stomach cancer, and others.

How Do I Prepare For A Virtual Colonoscopy?

A virtual colonoscopy requires minimal preparation. Your preparation guidelines will be provided to you by your referring physician and our team at SJRA. You will be instructed to fast for a certain period of time prior to your appointment. You may be informed to take a laxative prior to your exam to flush out your bowels, which enables our radiologists to get the clearest and most accurate images possible.
