Guiding AI in Radiology: ESR's Recommendations for Effective Implementation of the European AI Act

This statement by the European Society of Radiology (ESR) AI Working Group outlines key policies of the EU AI Act pertaining to medical imaging. It provides specific recommendations for effective implementation, addressing gaps and uncertainties in AI literacy, classification rules, data governance, transparency, human oversight, quality management, and more. The ESR is committed to supporting the safe and impactful integration of AI for patient benefit.

Transforming Radiology with Responsible AI

The EU AI Act marks a pivotal moment for medical imaging, demanding a clear framework for AI integration. Our analysis highlights key areas where strategic implementation can unlock significant benefits, enhancing diagnostic accuracy and operational efficiency while upholding patient safety and ethical standards.

The AI Act Article 4 emphasizes the critical importance of AI literacy for all stakeholders, including healthcare professionals and patients. The ESR aims to promote AI literacy and public awareness of AI benefits, risks, safeguards, rights, and obligations. Recommendations include developing codes of conduct for AI in imaging, integrating AI training into medical school and residency curricula, and continuous medical training for the existing workforce. This ensures effective and ethical utilization of AI technologies.

Medical devices regulated by the EU MDR automatically fall under the 'high-risk AI' category of the AI Act (Article 6, Annex III). Specific use cases, like imaging triage tools, should rightly be classified as high-risk due to their potential impact on decision-making and patient harm. The ESR recommends developing clear guidelines and practical examples for high-risk AI applications in radiology, ensuring clarity for their safe deployment.

Article 10 highlights the paramount importance of data governance and quality. High-risk AI systems must be developed using representative datasets reflecting geographical and contextual settings. The European Health Data Space (EHDS) is crucial for creating GDPR-compliant datasets for AI development. Transparency (Article 13) requires providers to supply detailed instructions and 'model cards' outlining AI system capabilities, limitations, and potential biases.

Article 14 mandates human oversight for high-risk AI systems, ensuring patient trust and high-standard care. This requires adequately trained professionals and research into mental load to define effective oversight thresholds. Quality Management Systems (QMS) requirements (Article 17) should be harmonized with EU MDR to streamline compliance for 'high-risk' medical AI tools, ensuring unified documentation.

Unacceptable Risk: Prohibition
High Risk: Conformity Assessment, Post-Market Monitoring
Limited Risk: Information & Transparency Obligation
Low & Minimal Risk: No Specific Regulations

AI Act vs. EU MDR: Harmonization Needs

Feature EU AI Act EU Medical Device Regulation (MDR)
Regulatory Focus
  • Regulates AI systems across sectors, focusing on safety, fundamental rights, and ethical implications.
  • Regulates medical devices throughout their lifecycle, ensuring safety and performance for patient health.
Risk Classification
  • Categorizes AI systems based on their potential for harm, with medical devices being 'high-risk'.
  • Classifies devices based on risk (I, IIa, IIb, III), impacting conformity assessment routes.
Quality Management System (QMS)
  • Introduces QMS requirements (Article 17) for high-risk AI, covering data governance, transparency, risk management, bias mitigation.
  • Requires a QMS (Article 10) for all medical device manufacturers, emphasizing safety, efficacy, and efficiency.
Post-Market Surveillance
  • Mandates post-market monitoring proportionate to AI system nature, with data collection by providers or deployers.
  • Mandates a robust post-market surveillance system and clinical follow-up for all medical devices.

Ensuring Human Oversight in AI-Driven Diagnostics

A major European hospital integrated an AI system for preliminary analysis of chest X-rays, flagging potential abnormalities for radiologist review. Initially, radiologists reported increased cognitive load due to over-reliance on AI suggestions, leading to 'automation bias'. The ESR's recommendations on AI literacy and human oversight thresholds were implemented. Radiologists underwent specialized training, focusing on interpreting AI outputs critically and understanding its limitations. Research into mental load helped define optimal review workflows. This led to a significant reduction in diagnostic errors caused by over-reliance and improved overall diagnostic accuracy and efficiency, reinforcing the critical role of human expertise alongside AI.

Your AI Implementation Roadmap

A strategic phased approach to integrate AI responsibly and effectively into your organization.

Phase 1: AI Literacy & Training Programs

Develop and implement comprehensive AI literacy programs for all radiology personnel and patients. This includes specific training for radiologists to ensure critical understanding and mitigate deskilling risks, alongside public awareness campaigns on AI benefits and risks.

Phase 2: Establish High-Risk AI Guidelines

Collaborate with regulatory bodies to define clear classification rules for high-risk AI in medical imaging, particularly for triage tools. Develop practical examples and best practices for safe deployment, ensuring all stakeholders have clarity on compliance requirements.

Phase 3: Data Governance & EHDS Integration

Implement robust data governance frameworks to ensure high-quality, representative datasets for AI development. Actively support the implementation of the European Health Data Space (EHDS) to facilitate GDPR-compliant data sharing for AI training and validation.

Phase 4: Harmonize Quality Management Systems

Work towards harmonizing QMS requirements between the EU AI Act and EU MDR. This will streamline compliance, unify documentation for high-risk AI medical devices, and provide clear guidance for implementation in radiology practices.

Phase 5: Post-Market Monitoring & Sandboxes

Establish infrastructures for tracking AI usage and potential adverse effects at a population level. Advocate for high-quality, multicenter clinical studies for AI product approval, moving beyond limited regulatory sandboxes, and ensure AI expertise in national competent authorities.
