What is difference between colonoscopy and barium enema in terms of information?

Significant. Colonoscopy is a direct look at the lining of the colon vs an indirect x-ray shadow of a barium enema (be). If something is seen on a colonoscopy, it can be treated or biopsied. The be can miss things in the rectum and should include a flex sig to evaluate that area. You are sedated for a colonoscopy. No sedation for a be. Both are acceptable measures for colon cancer screening.
Details. During a colonoscopy, it is possible to examine the colon in detail and obtain biopsies or remove the polyps if found. A barium enema, provides an image with relative low resolution. If something is found on the barium enema, a colonoscopy is necessary in order to determine what it is.

What is the difference between a barium enema and a virtual colonoscopy?

CT colonoscopy. Is a CT scan with specific technical parameters. There is a bowel prep to clear out the colon, and a tube is placed into the rectum to fill the colon with air. A barium enema uses x-ray/fluoroscopy instead of CT. With a rectal tube, the colon is filled with barium and air, and the patient placed in different positions for viewing. Barium enema has been largely replaced by colonoscopy.

What is the difference between a barium enema and a CT colonoscopy?

A barium enema has. Slightly more radiation exposure, requires you to flip and turn on the table until the radiologist is satisfied with the images, and in the end reveals slightly less information than the CT. The CT requires slightly less radiation exposure, allows you to lie flat on your back, and gives the radiologist more internal information. But a traditional colonoscopy is the first choice.
