Dr. Jean-Mathieu Beauregard is Assistant Professor in the Department of Radiology and Nuclear Medicine at Université Laval and Clinician-Scientist at CHU de Québec in Quebec City, Canada. He has a 12-year experience in radionuclide therapy based on quantitative imaging, including PET and SPECT. During his fellowship at the Peter MacCallum Cancer Centre, he developed his expertise in molecular imaging and radionuclide therapy of neuroendocrine tumours. Upon his return to CHU de Québec, he started a PRRT program and, more recently, launched a first-of-its-kind prospective clinical trial of personalized Lu-177-octreotate PRRT. Through this trial, quantitative SPECT-based dosimetry methods will be optimized in collaboration with a team of physicists. Dr. Beauregard also conducts a pre-clinical research program in which he investigates the application of novel radiosensitizing approaches for radionuclide therapy. Besides, he is also involved in molecular imaging research in the fields of prostate cancer and dementia.
