Summary
Pelvic magnetic resonance imaging (MRI) is a valuable tool for detecting and planning surgery for colorectal cancer local recurrence. MRI provides detailed anatomical and functional information, aiding in surgical strategy and follow-up.
Area of Science:
- Oncology
- Radiology
- Medical Imaging
Background:
- Current colorectal cancer surveillance relies on tumor markers, colonoscopy, and CT scans.
- Pelvic MRI and PET-CT are crucial second-line imaging modalities for assessing local recurrence.
Purpose of the Study:
- To review the clinical practice and applications of pelvic MRI in assessing colorectal cancer local recurrence.
- To highlight MRI's role in surgical planning and follow-up of treated recurrence.
Main Methods:
- Review of current literature on pelvic MRI for colorectal cancer recurrence.
- Discussion of MRI's diagnostic capabilities, including anatomical and diffusion-weighted imaging.
Main Results:
- Pelvic MRI accurately detects pelvic colorectal recurrence.
- MRI predicts the absence of tumoral invasion in pelvic structures, aiding surgical planning.
- MRI is useful for follow-up of recurrence treated with radiofrequency ablation.
Conclusions:
- Pelvic MRI is a key imaging modality for colorectal cancer local recurrence assessment.
- Integrating MRI findings with clinical data in a multidisciplinary setting is essential.
- MRI provides a preoperative roadmap for surgical intervention and post-treatment monitoring.
