camera is inserted through the entire colon.
In this procedure, a thin, flexible tube is inserted into the rectum to gently inflate the colon with air or carbon dioxide. This inflation expands the intestinal wall, thus improving image quality. The patient then lies on a table that moves through the CT scanner, which creates various cross-sectional images from different angles.
Using sophisticated computer software, these images are reconstructed into a virtual model of the colon’s interior, allowing radiologists to examine the intestinal wall without direct visualization of polyps, tumors, or
