Imaging technicians working with magnetic resonance imaging (MRI) may experience acute effects such as vertigo or dizziness when being exposed. A previous study also reported an increased risk of accidents in MRI exposed staff.
We aimed at evaluating commuting accident risk in Dutch imaging technicians.
Of invited imaging technicians, 490 (29%) filled in a questionnaire pertaining to (near) accidents when driving or riding a bike, health, lifestyle and work practices. We used logistic regression to evaluate the association between exposure to MRI-related electromagnetic fields and risk of commuting (near) accidents in the year prior to the survey, adjusted for a range of potential confounders.
Our cross-sectional study indicated an increased risk of (near) accidents if imaging technicians had worked with MRI in the year prior to the survey (odds ratio OR 2.13, 95%CI 1.23-3.69). Risks were higher in persons who worked with MRI more often (OR 2.32, 95%CI 1.25-4.31) compared to persons who worked sometimes with MRI (OR 1.91, 95%CI 0.98-3.72), and higher in those who had likely experienced higher peak exposures to static and time-varying magnetic fields (OR 2.18, 95%CI 1.06-4.48). The effect was seen on commuting accidents that had occurred on the commute from home to work as well as accidents from work to home or elsewhere.
Imaging technicians working with MRI scanners may be at an increased risk of commuting (near) accidents. This result needs confirmation and potential risks for other groups (volunteers, patients) should be investigated.
从事磁共振成像（MRI）工作的影像技师在接触过程中可能会出现眩晕或头晕等急性症状。先前的一项研究还报告称，接触MRI的工作人员发生事故的风险增加。
我们旨在评估荷兰影像技师在通勤过程中的事故风险。
在受邀的影像技师中，490人（29%）填写了一份关于开车或骑自行车时（近）事故、健康、生活方式和工作习惯的问卷。我们使用逻辑回归来评估在调查前一年接触MRI相关电磁场与通勤（近）事故风险之间的关联，并对一系列潜在混杂因素进行了调整。
我们的横断面研究表明，如果影像技师在调查前一年从事MRI工作，则（近）事故风险会增加（优势比OR 2.13，95%置信区间1.23 - 3.69）。与有时从事MRI工作的人员（OR 1.91，95%置信区间0.98 - 3.72）相比，更频繁从事MRI工作的人员风险更高（OR 2.32，95%置信区间1.25 - 4.31），并且在可能经历更高静态和时变磁场峰值暴露的人员中风险更高（OR 2.18，95%置信区间1.06 - 4.48）。这种影响在从家到工作的通勤过程中发生的事故以及从工作到家或其他地方的事故中都有体现。
操作MRI扫描仪的影像技师在通勤（近）事故中的风险可能会增加。这一结果需要得到证实，并且应该对其他群体（志愿者、患者）的潜在风险进行调查。
