| Summary: | "Magnetic Resonance Imaging (MRI) is a rapidly developing diagnostic technology that provides an unmatched view inside the human body without applying ionizing radiation. Improved image quality and novel applications, however, generally require higher electromagnetic field (EMF) strengths and faster image acquisitions, both of which may result in an increase in the EMF exposure of patients and workers. Over the past 30 years, safety standards limiting human exposure to EMFs were developed by agencies (e.g., FDA [1] and NRPB [2]-[5]) and product standard organizations [6] to specifically address the safety of patients undergoing MRI scans as well as by standard bodies like ICNIRP [9]-[12] and ICES [7],[8] to establish safety limits covering the entire spectrum from DC to light. The MRI exposure guidelines are mainly based on specific research results on nerve stimulation by induced low frequency currents, whereas the latter standards are based on biological experiments conducted at different frequencies and conditions and that have been extrapolated to the entire spectrum including the MR relevant frequencies. Inconsistencies inevitably resulted, although no attempt was ever made to resolve them with targeted research projects. ..." |
