Dr. Savvas Nicolaou

Dr. Savvas Nicolaou, FRCPC is the Director of Emergency and Trauma Imaging at Vancouver General Hospital, as well as a Professor of Radiology at the University of British Columbia.  He is also the UBC Vice-Chair of undergraduate education and continuous professional development. He completed his medical degree at the University of Toronto, and residency in Diagnostic Radiology at University of British Columbia.

Dr. Nicolaou is often credited with being the Father of the Canadian Emergency Radiology sub-specialty as he developed the first emergency/trauma radiology fellowship program at Vancouver General Hospital in 1998. Since then, he has trained over 80 fellows internationally, many of whom went on to start their own programs to serve the global community.

Within UBC Faculty of Medicine, he has been involved as the Director of the Undergraduate Radiology Education, where he has helped to integrate radiology into the medical curriculum. He has been the recipient of many teaching awards and was presented with the UBC Killam Teaching Prize in 2013, which recognizes all aspects of outstanding teaching at both the undergraduate and graduate levels. He was also awarded the prestigious Royal College Regional Awards – Region 1 Prix d’Excellence Specialist of the year in 2018 and Mentor of the year in 2013.

Dr. Nicolaou continues to contribute to the field of emergency radiology, publishing over 170 articles and over 400 abstracts in peer-reviewed conferences. Dr. Nicolaou’s enormous contributions to Emergency radiology was recognized by the American Society of Emergency Radiology as he was named Fellow of the ASER society in 2018, making him the first Canadian Fellow of the society to receive this prestigious award. Using state-of-the-art imaging technology, he is relentlessly investigating ways to develop faster, safer, and more sensitive methods for diagnosing patients in the acute care setting. Major focus areas of research in the acute care setting are on Ultra Low dose techniques, Dual Energy CT, Polytrauma Imaging, Brain Perfusion in trauma and the role of MRI and Artificial Intelligence.

In light of COVID19, Dr. Nicolaou has teamed up with Amazon AWS to deploy an open-source predictive and prognostic machine learning tool, which has brought together the global health care community to benefit all institutions fighting this pandemic, offering equitable access to technology in the most vulnerable systems.
