How frequently should CTC be performed?
There is little long-term data on the optimal frequency at which CTC should be performed. However, according to joint guidelines from the American Cancer Society (ACS), the US Multi-Society Task Force on Colorectal Cancer, and the American College of Radiology (ACR), CTC should be performed every 5 years, similar to double-contrast barium enema. This is compared to every 10 years for OC among patients with no polyps.
What is the role of routine computed tomography (CT) and magnetic resonance imaging (MRI) in colon cancer screening?
None.
