Andrew J. Fagan

Andrew J. Fagan, Ph.D., is a Professor of Medical Physics in the Department of Radiology at Mayo Clinic. He specializes in advancing ultrahigh-field magnetic resonance imaging (MRI) techniques, particularly at 7 Tesla (7T), to enhance diagnostic accuracy and reduce scan times. His work focuses on clinical applications of 7T MRI for neuro and musculoskeletal (MSK) imaging, MRI safety protocols, radiofrequency coil development, and quantitative MRI techniques. Dr. Fagan chairs multiple committees at Mayo Clinic, including the 7T MRI Safety Subcommittee and Technical User Group, ensuring cutting-edge MRI practices are safely implemented.

Education:

• Ph.D. in MRI Physics, University of Aberdeen (2004)
• Postgraduate Fellowship in Medical Physics, Trinity College Dublin (1997)
• MSc in Experimental Physics, Trinity College Dublin (1994)
• BSc (Hons) in Physics, Trinity College Dublin (1992)

Research Interests: Dr. Fagan’s research integrates advanced MRI technologies with clinical needs. Key areas include:

• Development of parallel transmit and deuterium metabolic imaging techniques at 7T
• Optimization of radiofrequency coils for MSK extremity imaging
• Reducing scan times using advanced acquisition acceleration
• Collaborative work with neurosurgery teams for pre-surgical planning
• Exploring sodium MRI for early stroke detection and tumor therapy monitoring

His work bridges physics and clinical practice, aiming to expand 7T MRI accessibility and improve patient care.

Publications & Awards: With over 90 peer-reviewed articles and book chapters, Dr. Fagan’s contributions span MRI safety, technical innovation, and clinical applications. He is a Fellow of the Institute of Physics (2016) and the Institute of Physics and Engineering in Medicine (2010), and has received awards such as the Best Oral Presentation at the Irish Association of Physicists in Medicine (2012) and the Astra-Zeneca Prize (2009).

Grants & Labs: Dr. Fagan collaborates on projects funded by institutions like Mayo Clinic and the National Institutes of Health. His work is supported by interdisciplinary teams in radiology, physics, and biomedical engineering. He leads initiatives to standardize 7T MRI protocols and improve clinical workflows.
