Effects of Exposure to Magnetic Fields in MRI: A Review of Current Evidence and Future Directions
Abstract
Purpose: This review aims to examine the biological effects of Magnetic Resonance Imaging (MRI) exposure in healthcare professionals working with high-field MRI systems (1.5 Tesla and above). By synthesizing current evidence, it seeks to inform future safety guidelines and highlight potential risks associated with cumulative, long-term exposure among MRI technicians and radiologists. Materials and Methods: A systematic literature search was conducted on studies published from 2000 to 2024. Databases (e.g., PubMed, Scopus) were queried using key terms such as “MRI exposure,” “occupational health,” and “high-field MRI.” Studies were evaluated based on methodological rigor, relevance to occupational settings, and reported biological effects. The search aimed to identify both short-term and long-term physiological impacts of repeated MRI exposure. Results: Although short-term MRI exposure is generally safe, healthcare workers consistently operating high-field MRI systems may experience transient sensory disturbances (e.g., vertigo, nausea) and possible long-term physiological effects. Findings suggest an elevated concern for cumulative exposure, yet conclusive evidence on the magnitude and nature of these risks remains limited due to variability in study designs and outcomes. Conclusion: While MRI technology plays a pivotal role in diagnostic medicine, ongoing research is needed to clarify the occupational hazards for healthcare professionals exposed to high-field environments. Improved monitoring, standardized safety protocols, and comprehensive longitudinal studies are recommended to ensure the continued safe use of MRI in clinical settings
