Highlights |
• | Magnetic resonance imaging (MRI) is the gold standard imaging modality for rectal cancer staging as it guides patient management. |
• | Knowledge of normal anatomy and terms used for rectal cancer staging is critical. |
• | Standardized reporting is one key element to improve quality and reproducibility in radiology report for MRI of rectal cancer. |
Abstract |
Purpose |
To develop French guidelines by experts to standardize data acquisition, image interpretation, and reporting in rectal cancer staging with magnetic resonance imaging (MRI).
Materials and methods |
Evidence-based data and opinions of experts of GRERCAR (Groupe de REcherche en Radiologie sur le CAncer du Rectum [i.e., Rectal Cancer Imaging Research Group]) and GRECCAR (Groupe de REcherche en Chirurgie sur le CAncer du Rectum [i.e., Rectal Cancer Surgery Research Group]) were combined using the RAND-UCLA Appropriateness Method to attain consensus guidelines. Experts scoring of reporting template and protocol for data acquisition were collected; responses were analyzed and classified as “Recommended” versus “Not recommended” (when ≥ 80% consensus among experts) or uncertain (when < 80% consensus among experts).
Results |
Consensus regarding patient preparation, MRI sequences, staging and reporting was attained using the RAND-UCLA Appropriateness Method. A consensus was reached for each reporting template item among the experts. Tailored MRI protocol and standardized report were proposed.
Conclusion |
These consensus recommendations should be used as a guide for rectal cancer staging with MRI.
