RESUMO
PURPOSE: To investigate the level of noise that magnetic resonance (MR) technologists are exposed to during daily tasks, and prevalence of hearing loss among MR technologists. METHODS: Decibel levels at the scanner control panel were measured and recorded at clinical facilities. A survey was distributed to MR technologists, which included questions about demographics, workplace habits, and self-reported hearing loss. RESULTS: Technologists are exposed to decibel levels higher than U.S. government recommended occupational limits; however, these are for very short periods, resulting in an average projected 8-hour noise dose of 1.68%. Statistical analysis of survey results showed no association between time spent working in an MR imaging department (P = .111); however, results did show an association between entering the scan room during image acquisition and hearing loss (P = .005). DISCUSSION: At times, technologists are exposed to decibel levels exceeding the U.S. Occupational Safety and Health Administration and the U.S. Food and Drug Administration recommended limits; however, the average findings indicate that there is a low risk of hearing damage from working at the control panel. Statistical analysis revealed an association between entering the scan room and hearing loss; therefore, individuals entering the scan room for any reason should be wearing hearing protection, even for short periods. CONCLUSION: Risks of exposure to high occupational decibel levels should be monitored continually. This study provides a foundation for future research studies, such as longitudinal analysis of hearing loss in MR technologists.
