Background: High-resolution magnetic resonance imaging is the principal imaging modality for local staging and preoperative risk
stratification of rectal cancer. Its value extends beyond conventional tumor–node–metastasis classification by identifying prognostically important features that influence neoadjuvant treatment selection, surgical planning, and the feasibility of sphincter-preserving approaches. These features include tumor relationship to the mesorectal fascia, depth of extramural invasion, extramural venous
