The aim of the exhibit is to: • Illustrate the anatomical information provided by rectal magnetic resonance imaging (MRI). • Discuss the protocols and the technical requirements. • Understand the MRI findings used to stage rectal cancer based on the TNM classification and other relevant prognostic factors, before and after neoadjuvant radiochemotherapy (RCT), with pathologic correlation. • Aknowledge and illustrate the importance of MRI for surgical planning. • Discuss the current role of diffusion weighted imaging (DWI) in the restaging after neoadjuvant RCT. • Summarize essential findings that should be searched for and included in the radiologist report.    

• Introduction Up-to-date on the current state-of-the-art treatment options. Discussion of the pivotal role of rectal MRI in the individualization of treatment by providing an accurate stratification of risk. • Normal anatomy and MRI technique/protocol Role of DWI and volumetry after RCT is discussed. • Illustration of the relevant imaging findings based on the TNM classification and other important prognostic factors with pathologic correlation. • Discussion of the items that should be included in a structured report, with review of the literature. • Conclusion.
