CT Colonography
CT colonography, also known as virtual colonoscopy, is a medical imaging technique used to examine the colon (the large intestine) for signs of disease, such as polyps or cancer. During the procedure, a small tube is inserted into the rectum to gently inflate the colon with air or carbon dioxide. A CT scan then captures detailed images of the colon's interior. This non-invasive test can detect abnormalities without the need for traditional colonoscopy, which involves a longer procedure. It’s often used as a screening tool for individuals at risk of colorectal issues.

CT colonography, also known as virtual colonoscopy, is a medical imaging technique that uses computed tomography (CT) scans to create detailed pictures of the colon and rectum. Patients undergo a preparation process to clear the bowel, and then a CT machine takes images after air and sometimes a contrast material are introduced into the colon. This procedure helps doctors detect abnormalities such as polyps or tumors without the need for traditional colonoscopy. It’s a non-invasive option that can provide valuable information about colon health, particularly for colorectal cancer screening.
