Abstract
Rectal cancer has a high incidence in our area. The different treatment options that can be used in each case depend fundamentally on the extension of the tumor at the time of diagnosis. Thus, radiologists have a central role in the management of this disease. We discuss the optimum imaging technique for staging rectal cancer, some fundamental histological aspects, and the accepted semiology in the interpretation of different imaging studies carried out in these patients, as well as the diagnostic performance of each technique. We provide a general overview of the prognosis and different treatment options. This knowledge is very useful for radiologists participating in multidisciplinary teams and for understanding the transcendence of the information provided by image interpretation in these patients.
