Synopsis

MR imaging for rectal cancer plays a key role in driving management decisions by assisting the multidisciplinary team colorectal cancer team. The decision for surgery +/- neoadjuvant chemotherapy is based on tumor staging on MRI. Good quality rectal cancer MRI protocol and standardized reporting enables the radiologist (a) To provide rectal cancer staging with T and N categories (b) To describe cancer location thereby directing surgical method of choice (c) detect the presence of extramural vascular invasion (EMVI) (d) delineate tumor extension in the mesorectal fascia and (e) identify tumor infiltration into anal sphincter complex in low rectal cancers.

  • Discuss the details of rectal anatomy which is the basis of local staging of rectal cancer at MRI.
  • Discuss standard rectal MRI protocol for primary tumor staging.
  • Discuss in detail TNM staging of rectal cancer.
  • Outline keypoints for radiologic report for primary staging.
