Virtual Hands-On MRI Training Enhances Confidence and Performance in Rectal Cancer Staging

Overview

A novel virtual hands-on training course combining case-based learning, webinars, and expert feedback significantly improved radiologists' diagnostic performance, confidence, and interobserver reproducibility in MRI staging of rectal cancer. The course demonstrated feasibility and potential to overcome limitations of traditional face-to-face training.

Background

MRI is the standard imaging modality for local staging of rectal cancer, critical for guiding multidisciplinary treatment decisions. Radiologists' diagnostic accuracy depends heavily on experience and dedicated training, with hands-on feedback shown to be more effective than lectures alone. The COVID-19 pandemic disrupted conventional training, accelerating the adoption of virtual education platforms. This study evaluated a newly developed virtual hands-on course integrating interactive case review and expert teaching to improve radiologists' MRI staging skills.

Data Highlights

Sixty-five radiologists from 24 countries participated in the course. The training included 70 cases for practice and 7 test cases for pre- and post-course assessment. Expert consensus staging and annotated key images were provided as feedback. Participants completed a pre-course test without access to teaching materials or feedback to establish baseline performance and confidence levels.

Key Findings

• The virtual hands-on course combined individual case-based training with webinars and expert feedback via a dedicated web platform (iScore).
• Participants showed improved diagnostic performance in MRI staging and restaging of rectal cancer after the course.
• Confidence in interpreting challenging cases increased, with participants rating cases as easier to stage post-training.
• Interobserver reproducibility among radiologists improved, indicating more consistent staging assessments.
• The course leveraged structured reporting templates, video lectures, and annotated images to enhance learning.
• The virtual format allowed international participation and overcame logistical challenges of face-to-face training.

Clinical Implications

This virtual hands-on training model offers an effective and scalable approach to enhance radiologists' expertise in rectal cancer MRI staging, which is crucial for optimal patient management. Incorporating structured feedback and expert guidance in a virtual environment can maintain and improve diagnostic quality, especially when traditional training opportunities are limited. Such programs may be integrated into ongoing professional development and multidisciplinary team education.

Conclusion

The study supports the feasibility and positive impact of a virtual hands-on training course on radiologists' confidence and performance in rectal cancer MRI staging. This innovative educational approach holds promise for improving diagnostic accuracy and patient care globally.
