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.

CONCLUSIONS: Postesophagectomy paraconduit hernia is more common after totally minimally invasive esophagectomy compared with open or hybrid […]
- CT Abdominal Tomography Indications: Are We All Sticking to the Plan?
CONCLUSIONS: There has been no "indication creep" for CT abdominal tomography over time.
- Dual-energy CT in diffuse liver disease: is there a role?
Dual-energy CT (DECT) can be defined as the use of two different energy levels to identify and quantify material composition. Since its inception, […]
- Ultra-low dose CT abdomen and pelvis for the detection of acute abdominal pathology in the emergency room: initial experience from an academic hospital
CONCLUSION: With its high clinical yield and similar radiation dose, ULDCT appears as a suitable alternative to abdominal radiography for the […]
- Comparison of conventional chest x ray with a novel projection technique for ultra-low dose CT
CONCLUSION: Thoracic tomograms were found to be diagnostically superior to CXR for focal lung disease, at no increased radiation dose. The thoracic […]
- Evaluation of Lymphadenopathy and Suspected Lymphoma in a Lymphoma Rapid Diagnosis Clinic
CONCLUSION: Establishing a nurse practitioner-led LRDC was effective in shortening time to diagnosis of lymphoma. Younger age, smaller lymph node […]

- Frailty assessment prior to thoracic surgery for lung or esophageal cancer: a feasibility study
CONCLUSIONS: Frailty assessment is feasible in the pre-operative outpatient setting and had a high degree of acceptance among surgeons and patients. […]
- Helical CT with variable target noise levels for dose reduction in chest, abdomen and pelvis CT
CONCLUSION: Contiguous helical scanning of the chest/abdomen/pelvis with variable target noise levels results in approximately 17% dose reduction if […]
