Can you detect colon cancer?

Our MRI scans the abdominal and pelvic region, which means large colorectal masses may be visible as incidental findings. However, MRI is not a reliable screening tool for colon cancer, especially in early stages.

The gold standard for colon cancer screening is a colonoscopy, which allows direct visualization of the bowel lining and removal of precancerous polyps. Small polyps and early-stage mucosal changes are generally not visible on MRI due to bowel movement and gas artifacts.

If you're over 50 or have a family history of colorectal cancer, we strongly recommend discussing screening colonoscopy with your GP. Our screening is complementary and may catch advanced disease, but it's not a substitute for colonoscopy.
