Core Tip

Core tip: Computed tomography (CT) scans are increasingly used in the followup of patients with colorectal cancer. As multimodality treatments have become more successful in treating patients with metastatic disease follow up regimes have become more intensive. However current published treatment guidelines do not give a clear indication of the optimal frequency of follow up imaging. This review summarises the adverse effects associated with frequent use of CT scans in patient follow up.
