Overview
This course outlines the challenges in rectal cancer imaging. The speakers will provide an overview over the anatomy, the important structures, treatment guidelines, questions to be answered by imaging, and imaging techniques.

Target Audience
Radiologists, technologists performing MRI of rectal cancer; scientists researching rectal cancer imaging including sequence development and post-processing.

Educational Objectives
As a result of attending this course, participants should be able to:
- Name the important features influencing the therapeutic decision;
- Describe the diagnostic features of rectal cancer;
- Apply MRI criteria for diagnosis and staging of rectal cancer; and
- Assess new techniques and applications for rectal imaging.

		Treatment Challenges: What Does the Surgeon Need to Know? Brian Allen Watch the Video Colorectal carcinoma is the third leading cause of new cancer and cancer-related death in the United States. Prognosis is related to depth of invasion and ability to achieve a negative circumferential resection margin at surgery. Total mesolectal excision and neoadjuvant therapy for locally advanced cancer has been shown to improve local oncologic control. MRI allows good differentiation of T2 and T3 tumors and can define the circumferential resection margin for surgical planning. Accuracy for nodal metastatic disease can be improved by using both size and morphology criteria. Following neoadjuvant therapy, MRI can be used to assess treatment response.
		Diagnostic Challenges in Rectal Cancer: What Do We Need to Answer? Kirsten Gormly Watch the Video Rectal MRI is a critical part of the patient pathway. Correct technique and understanding of the key reporting elements is critical. This presentation covers T2 technique, how to report staging and restaging MRI scans and tips for interpretation of challenging areas.
