and PET/CT Ville Marie Centre
Dr. Beaulieu is a nuclear medicine specialist board certified in Quebec and in Canada who holds a license to practice medicine in the province of Quebec and in the state of Washington. He is an assistant professor in the Department of Radiology, Radio-Oncology and Nuclear medicine at the Université de Montréal and is responsible for undergraduate teaching. He practices nuclear medicine at the Centre hospitalier de l’Université de Montréal (CHUM), with emphasis on PET/CT.
Dr. Beaulieu completed 2 years of further training in PET, including an18-month fellowship at the University of Washington’s Hospital in Seattle, USA, from 2001 to 2003. There, he had the opportunity to learn from world renowned experts by reading the results of thousands of PET examinations and by performing anatomical correlations with the results of an equal number of radiological examinations, mainly CT scans and MRI examinations. During his further training, he was a main investigator in a research project financed by the National Institute of Health concerning the use of a new radioactive molecule to detect prostate cancer through PET imaging.
Dr. Beaulieu is author or co-author of 19 articles or abstract, mostly about PET imaging. He presented the results of his research at different international nuclear medicine conferences and to several university hospital centres throughout Canada.
Dr. Beaulieu has expertise with regard to the various quantification methods used in PET imaging for clinical or research purposes, and to the evaluation of the new radioactive molecules allowing the detection of prostate cancer through PET scans.

 Caroline SAMSON M.D., FRCP(C)
Dr. Samson is a diagnostic radiologist board certified in Quebec, in Canada and in the United States. She is an assistant professor in the Department of Radiology, Radio-Oncology and Nuclear medicine at the Université de Montréal. She practices diagnostic radiology at the Hôpital du Sacré-Coeur de Montréal, a trauma centre affiliated with the Université de Montréal. Her fields of expertise are numerous, most prominently abdominal imaging.
Dr. Samson completed a 1-year fellowship in whole-body magnetic resonance imaging (MRI) at the Detroit Medical Center of Wayne State University, in Michigan. Her first research work involved the comparison of the effectiveness of PET imaging and that of MRI in abdominal imaging. Since 1998, she focuses more specifically on breast and colon cancer screening. She is one of the pioneers in virtual colonoscopy in the province of Quebec.
Dr. Samson is often asked to appear as guest speaker by various associations in the fields of physics, medicine, oncology, radiology, surgery and gyneco-obstetrics. She is actively involved in teaching, from anatomy classes at the university level to training for certified radiologists through the Société canadienne-française de Radiologie. In 2003, she was named teacher of the year in radiology.

 Oussama NACHAR M.D., FRCP(C)
Dr. Oussama Nachar is a nuclear medicine specialist with an expertise in PET/CT, certified in Quebec by the Collège des médecins du Québec, in Canada by the Royal College of Physicians and Surgeons of Canada (RCPSC) and in the United States by the American Board of Nuclear Medicine (ABNM). Dr. Nachar holds a license to practice medicine in the province of Quebec as well as in several American states such as Texas, Virginia, Vermont, and Louisiana.
Dr. Nachar, who is renowned internationally, has acquired a vast experience with regard to the use of PET imaging in oncology, neurology and cardiology, with several thousand cases interpreted in PET and PET/CT. After his fellowship studies, Dr. Nachar occupied a staff position at the University of Texas Southwestern Medical Center at Dallas, Texas, and, subsequently, at the Medical College of Virginia in Richmond, Virginia. He is currently the section head of the Department of Nuclear Medicine and PET/CT at the Ochsner Health System, in New Orleans, Louisiana. He is also professor at the Ochsner Heart and Vascular Institute, and supervises the training of more than 45 residents and fellows in radiology and cardiology.
Dr. Nachar is a clinician-scientist who has conducted several basic research projects and clinical studies. A large portion of this work deals with breast cancer, more particularly with ways to improve the screening and characterization of the disease. He is one of the pioneers in the field of estrogen receptor imaging of breast cancer, and was thus granted a Ph.D in radiobiology. Dr. Nachar is author and co-author of several articles regarding PET/CT which were published in world renowned medical journals. He has been invited to numerous national and international conferences to present the results of his research, and asked to give presentations and teach classes on several aspects of PET/CT.
Dr. Nachar is a member of the Board of Trustees of the Society of Nuclear Medicine (SNM), the most influential nuclear medicine association in the world.
