CT Colonography: A Less Invasive Virtual Colonoscopy Alternative

March observes Colorectal Cancer Awareness Month and doctors are advising the public to acquire the screening. However, a lot of them don’t feel like they want to get screened at some point in the uncomfortable process recognized as the colonoscopy. On the other hand, there are less invasive alternatives which include CT colonography moreover recognized as the virtual colonoscopy.

Dr. Michael Zalis of Massachusetts General Hospital, told WBZ News Radio 1030 last Wednesday, “Virtual colonoscopy is a great test. It’s a good data-supported test that performs the essential function of allowing people to get screened for an entirely preventable disease, which, as you know, is colon cancer.”

Intended for the conventional colonoscopy, citizens are required to drink four liters of a ready-made solution that aids in clearing out the colon.

“Typically for virtual colonoscopy, you are required to drink less of that fluid,” says Dr. Zalis.

The examination does detect polyps and if they are found, subsequently, you would probably have to obtain a conventional colonoscopy.

“The data now is very strong that virtual colonoscopy is a very accurate test for detecting those things. If you provide a virtual colonoscopy to people, how many people subsequently need to go on to get an optical colonoscopy? It turns out it’s only a very small fraction. Something around 12-to-15 percent of people of average risk who gets a virtual colonoscopy would have to get an optical subsequently to have something removed,” says Dr. Zalis.

“What that means is that about 80-to-85 percent of people who come to a virtual colonoscopy and get screened that way are done,” he added.

The Centers for Disease Control said that about 140,000 Americans are identified with colorectal cancer in a year and over 50,000 individuals die because of it.

Nevertheless, doctors say the illness is very much preventable. People should begin getting screened upon reaching the age of 50.
