This test is typically used for colon cancer screening and detection, as well as for evaluating patients with symptoms such as abdominal pain, rectal bleeding, or changes in bowel habits.
When this test is required
This test may be requested as a screening test for colon cancer, or as a diagnostic tool for evaluating patients with symptoms related to the colon or rectum.
What the Test Detects
CT colonography uses x-rays and computer technology to produce detailed images of the colon and rectum. These images can help detect polyps, tumors, or other abnormalities.
Preparation for the Test
Preparation for CT colonography typically involves bowel preparation to clean out the colon. This may include a special diet, laxatives, or enemas.
Sample Requirements
No sample is required for this test.
Additional Notes
CT colonography is a non-invasive test that does not require sedation, unlike traditional colonoscopy. However, if abnormalities are found during the test, a traditional colonoscopy may be necessary to obtain a tissue sample or remove polyps.
