MRI in rectal cancer: from precision staging to prognostic prediction

doi:10.3877/cma.j.issn.2095-3224.2026.01.003

Abstract

Abstract:

Magnetic Resonance Imaging (MRI) plays a pivotal role in the diagnosis and management of rectal cancer. Advancements in high-resolution sequences, functional imaging, and artificial intelligence have broadened MRI’s role from morphological staging to encompassing efficacy assessments, prognostic predictions, and guiding personalized treatment strategies. This review comprehensively examines the evolving role of MRI in the primary staging of rectal cancer (including T/N staging, extramural vascular invasion, tumor deposits, and mesorectal fascia assessment), the evaluation of treatment response following neoadjuvant therapy, and the prediction of survival outcomes. It also discusses the current challenges in MRI evaluation and offers insights into future directions, aiming to inform clinical practice and research.

Key words: Rectal cancer, Magnetic resonance imaging, Radiomics, Artificial intelligence, Precise diagnosis, Prognostic prediction
