Iterative Revisions of Barium Enema Description

Round 1: Original wording from (2).	Barium enema, or a lower GI series, is another test to check for colon cancer. X-rays are taken of the colon after barium or barium and air are given by enema. The day before the test you are asked to drink a lot of liquids and to take laxatives. No solid food is permitted.
Round 2	Barium enema, or a lower GI series, is another test to check for colon cancer. X-rays are taken of the colon after barium or barium and air are given by enema into your rectum. The day before the test you are asked to drink a lot of liquids and to take laxatives. No solid food is permitted.
Round 3	Another test to check for colon cancer is called barium enema, or lower GI series. Barium or barium and air are put into your rectum. While you hold in the barium, an x-ray is taken of the colon. This is different than an upper GI series, where you drink the barium before having an x-ray taken of your stomach or small intestines. To prepare for the barium enema, or lower GI series, you are asked to drink a lot of liquids and take laxatives the day before the test. No solid food is permitted.
Round 4: Final revision.	Another test to check for colon cancer is called barium enema, which is also known as a lower GI series. Barium or barium and air are put into your rectum by enema. You do not drink the barium. While you hold the barium in your rectum, an x-ray is taken of the colon. To prepare for the barium enema, you are asked to drink a lot of liquids and take laxatives the day before the test. No solid food is permitted.
