Professor Martin Graves to discuss MRI coil innovation and safety at London event

Professor of MRI physics Martin Graves from the University of Cambridge’s department of radiology will present at the MRI Safety Update and Innovations Day organised by MRI Safety Matters and taking place at the Royal College of Physicians, London, on October 31.

Professor Graves, who is also an honorary consultant clinical scientist at Cambridge University Hospitals NHS Foundation Trust, is an internationally recognised voice in MRI physics. He has published more than 240 peer-reviewed papers, co-authored several books and received numerous awards.

At this year’s event, he will explore the evolution of MRI coils, from relatively simple volume coils to today’s flexible multi-channel arrays and emerging coil innovations. Delegates can access the presentation in person, virtually or on demand. “Coils are really the interface between the patient and the MRI system,” he explained. “Their design therefore has a direct effect on signal-to-noise ratio, image quality, coverage, acceleration and, importantly, patient safety.”

Advances in coil technology have led to improved image quality and scanning efficiency but Professor Graves warned that while modern coils are safe when they are used correctly, there are more things for practitioners to understand. The safety concerns will be considered, including RF heating, cable routing, the significance of implants and the importance of routine inspection and an appropriate QA programme for proper maintenance of coils.

Professor Graves added that an MRI coil is “not simply something we place around the patient to improve the image,” but “an active part of the electromagnetic system surrounding the patient.” He said: “Good coil practice is both an image quality issue and a patient safety issue.”
