SF 5 - MRI of rectal carcinoma

Learning Objectives

1. Up to a third of rectal cancers undergoing chemoradiotherapy may achieve complete regression so that post-treatment MRI may save them from surgery.
2. The radiologist must increasingly understand the regression process and timing of the replacement of cancer by scar tissue.
3. Tumour regression grading (TRG) and its relationship to endoscopic and histological criteria must be understood. A new sign, the split scar (SSS), may be a predictor of the permanence of the regression.

Learning Objectives

1. To explain rectal cancer patient management in the Netherlands and the role of the radiologist in the multidisciplinary team.
2. To understand the importance of rectal cancer MRI and how MRI findings influence clinical decisions.
3. To discuss current pitfalls and challenges in rectal cancer imaging and ways to overcome them.

Learning Objectives

1. To offer an overview of advanced imaging techniques and new modalities applied in rectal cancer imaging.
2. To explain the advantages and drawbacks of different modalities.
3. To discuss future perspectives in imaging of rectal cancer.
