Abstract
Being the most common gastrointestinal cancer and the second most common cause of cancer deaths, colorectal cancer is a major health problem. Risk factors for colorectal cancer are variable and include dietary, hereditary, and environmental factors.
In recent years, the mortality rate has significantly decreased and 5-year survival has improved due to successful screening and early detection techniques as well as optimization of surgical techniques, new neoadjuvant therapies, and developments in diagnostic imaging modalities. Radiological imaging plays an important role in the screening, primary diagnosis, staging, management, evaluation of treatment response and follow-up of colorectal cancer.
Therapeutic options of colon cancer differ significantly from the rectal cancer. The treatment strategies differ depending on the staging of the disease and also for local/primary tumor management and management of distant metastatic disease. Therefore, imaging algorithms and preferred imaging modalities also differ substantially for colon and rectal cancers.
Significant advances have been made in imaging technologies over the last decades. Several imaging modalities are used, and each modality has its inherent advantages and limitations. Improvements in imaging technology will further play an important role in reducing the incidence and mortality of colorectal cancer as well as optimizing the patient management.
