Core Tip

Core tip: While encouraging progress has been made in the management of colorectal cancer (CRC), it still remains among the malignancies with higher incidence and mortality. Tomographic imaging plays a crucial role in the diagnosis, staging and evaluation of treatment responses in CRC; however, it may also conceal critical information that could guide treatment decisions. The quantitative analysis of computed tomography (CT), magnetic resonance imaging and positron emission tomography/CT images could unveil novel promising biomarkers in the form of numerical parameters. These parameters, if validated in terms of their clinical significance, may contribute to redefining the role of diagnostic imaging and improving CRC management.
