Patrik Rogalla, MD
Dr. Patrik Rogalla completed his medical studies as well as his radiology residency at the Free University of Berlin in Germany. After completing a Clinical fellowship in gastro-intestinal imaging at the University of California UCSF in the United States, he returned to Germany, where he began working at the Charité University Hospital. There, he progressively held roles, which eventually led him to his appointment as Professor of Radiology.
In July 2009, Dr. Rogalla was appointed as Full Professor of Radiology at the University of Toronto and held the position as Head of the Abdominal Imaging Division from July 2010 until December 2017. In February 2018, he was appointed as Head of the Cardiothoracic Imaging Division and Deputy Head of Innovation at JDMI. Furthermore, Dr. Rogalla is the Director of Computed Tomography at JDMI and served as the Site Director at the Princess Margaret Cancer Centre until June 2020 before assuming the Imaging Site Director role at the Toronto General Hospital.
Dr. Rogalla has published more than 169 original articles and several book chapters and holds two international patents; he is actively involved in many professional and international radiological societies. In June 2020, he graduated from the Rotman School of Business with an MBA in Health and Life Sciences.
