title: [The role of cross-sectional imaging in staging of rectal cancer].
abstract: The ongoing diversification of treatment strategies for rectal cancer justifies the demand for highly specialized radiological imaging. Currently, numerous studies have underlined the ability of magnetic resonance imaging (MRI) to determine those parameters that are critical for therapeutic decision-making and prognosis in rectal cancer. Computed tomography (CT) does not meet the criteria of a first line diagnostic procedure with regard to local staging but will remain the workhorse in the search for distant metastases. The increasing acceptance of extended MRI-based concepts will, however, improve cost-effectiveness and simplify patient management. Response evaluation and detection of recurrent disease are the major indications for positron emission tomography (PET)/CT, which is currently not routinely recommended.
