Virtual colonoscopy, also known as CT colonography, is a test that allows visualization of the intestine without inserting a probe with a colon tube and is useful for identifying intestinal polyps smaller than 0. 5 mm, such as diverticula or cancer.
Virtual colonoscopy is performed using low-dose computed tomography (CT) equipment and images are obtained that are analyzed by computer programs that generate images of the intestine from various perspectives, in an average of 15 minutes.
- During tests.
- A small tube was inserted into the initial part of the intestine for a year.
- To inflate the gas inside that helps dilate the intestine.
- Making the parts more visible.
If the images obtained during virtual colonoscopy are modified, the patient may perform a small surgery and the same procedure to remove the polyps, for example.
Virtual colonoscopy involves cleaning the intestine before the test, so that it is possible to visualize the inside, so that the day before the necessary tests:
This test could attack most patients, but could not be done due to radiation.
Virtual colonoscopy is used in people who cannot be under anesthesia and who do not tolerate colonoscopy after the introduction of the tube for a year, causing discomfort, some benefits of virtual colonoscopy are:
In normal colonoscopy, a tube is inserted within a year to see inside the intestine, even if there is a risk of perforation of the intestinal wall through the tube.
In addition, it can also diagnose alterations in the organs involved with the intestine, such as the liver, pancreas, gallbladder, stomach, bladder, prostate, and even the uterus, which examines it using CT scans. He knows more about CT.
