Pelvic MRI for Rectal Cancer: Tips on Interpretation

This case-based, one-hour interactive session is targeted toward surgeons involved in a multidisciplinary approach to rectal cancer care. It serves as an introduction to rectal MRI and the various interpretative assessments made at initial staging. Through a guided discussion between a colorectal surgeon and GI radiologist, the participant will be led through several cases, examining how interpretation decisions are made at MR and how various factors, including technical and patient-based characteristics, may impact the level of confidence in an imaging assessment. The participant will have opportunities to ask questions in real time as the cases are reviewed. Specific teaching points will be emphasized that should set a solid foundation regarding Rectal MR imaging for the surgeon.

Target Audience

Surgeons and other physicians, nurses, cancer registrars, and allied health professionals.

Learning Objectives

  • Identify key anatomic imaging landmarks helpful in rectal cancer staging at MR.
  • Critically evaluate whether tumor is contained or extends past the muscularis propria of the rectum.
  • State the imaging criteria used in determining lymph node positivity and how lymph node drainage patterns may impact interpretation.

Ineligible company

The ACCME defines an “ineligible company” as any entity producing, marketing, re-selling, or distributing health care goods or services used on or consumed by patients. Providers of clinical services directly to patients are NOT included in this definition.

Financial Relationships

Relationships in which the individual benefits by receiving a salary, royalty, intellectual property rights, consulting fee, honoraria, ownership interest (e.g., stocks, stock options or other ownership interest, excluding diversified mutual funds), or other financial benefit.  Financial benefits are usually associated with roles such as employment, management position, independent contractor (including contracted research), consulting, speaking and teaching, membership on advisory committees or review panels, board membership, and other activities from which remuneration is received, or expected.  ACCME considers relationships of the person involved in the CME activity to include financial relationships of a spouse or partner.

Conflict of Interest
