　　报告摘要： 

　　Magnetic resonance imaging (MRI) is a powerful, non-invasive diagnostic medical imaging technique widely used to acquire detailed information about anatomy and function of different organs in the body, in both health and disease. It utilizes electromagnetic fields of three different frequency bands: static magnetic field (SMF), time-varying gradient magnetic fields (GMF) and pulsed radiofrequency fields (RF). Some investigators have examined the genotoxic potential of MRI in human cells since increased genetic damage is positively correlated with carcinogenesis. The observations reported in MRI-exposed cells were controversial and the details will be discussed. 

　　报告人简介： 

　　Dr. Vijay is from the department of Radiology, University of Texas Health Science Center in San Antonio. She has over 25 years of research experience in examining the biological and health effects of non-ionizing radiofrequency fields (RF) in human and animal cells. She was invited by the International Agency for Research on Cancer as a member of expert group of scientists to evaluate the carcinogenicity of radiofrequency fields (RF) used for mobile communication devices. She is now reviewing the literature on genotoxic potential of RF for the World Health Organization report on Environmental Health Criteria. Her most recent research interest is in the examination of biological effects, especially, genetic damage in MRI-exposed human cells.
