Peter MacMahon

Peter MacMahon is a Clinical Professor at University College Dublin and a Consultant Radiologist at the Mater Hospital in Dublin. His work focuses on the integration of artificial intelligence (AI) into clinical radiology to improve diagnostic efficiency and patient outcomes in emergency settings.

• Specializes in emergency radiology, including trauma and stroke imaging
• Spearheaded AI implementation for stroke management at Mater Hospital since 2015
• Developing generative AI models to predict MRI outcomes from CT scans
• Advocates for balanced human-AI workflows to mitigate automation bias

His research leverages medical imaging data to address critical challenges in emergency care, such as reducing unnecessary patient transfers and improving clot detection rates by 100%. He collaborates closely with AI programmers and clinicians to ensure data quality and clinical relevance in AI development.

At Mater Hospital, he leads initiatives to deploy AI in X-ray diagnostics, aiming to streamline frontline care while maintaining rigorous clinical verification processes. His work spans musculoskeletal imaging, bone tumor analysis, and emergency condition diagnostics, with a focus on practical implementation in resource-constrained environments.
