Recent studies have consistently shown that amongst staff working with MRI, transient symptoms directly attributable to the MRI system including dizziness, nausea, tinnitus, and concentration problems are reported. This study assessed symptom prevalence and incidence in radiographers and other staff working with MRI in healthcare in the UK.
One hundred and four volunteer staff from eight sites completed a questionnaire and kept a diary to obtain information on subjective symptoms and work practices, and wore a magnetic field dosimeter during one to three randomly selected working days. Incidence of MRI-related symptoms was obtained for all shifts and prevalence of MRI-related and reference symptoms was associated to explanatory factors using ordinal regression.
Incident symptoms related to working with MRI were reported in 4% of shifts. Prevalence of MRI-related, but not reference symptoms were associated with number of hours per week working with MRI, shift length, and stress, but not with magnetic field strength (1.5 and 3 T) or measured magnetic field exposure.
Reporting of prevalent symptoms was associated with longer duration of working in MRI departments, but not with measured field strength of exposure. Other factors related to organisation and stress seem to contribute to increased reporting of MRI-related symptoms.
• Routine work with MRI is associated with increased reporting of transient symptoms • No link to the strength of the magnetic field was demonstrated. • Organisational factors and stress additionally contribute to reporting of MRI-related symptoms.
近期研究一致表明，在从事MRI工作的人员中，报告了直接归因于MRI系统的短暂症状，包括头晕、恶心、耳鸣和注意力不集中问题。本研究评估了英国医疗保健领域从事MRI工作的放射技师和其他人员的症状患病率和发病率。
来自8个地点的104名志愿者工作人员完成了一份问卷，并记日记以获取有关主观症状和工作习惯的信息，并且在随机选择的1至3个工作日佩戴磁场剂量计。通过序数回归获得所有班次的MRI相关症状发病率，并将MRI相关症状和对照症状的患病率与解释因素相关联。
4%的班次报告了与从事MRI工作相关的突发症状。MRI相关而非对照症状的患病率与每周从事MRI工作的小时数、轮班时长和压力有关，但与磁场强度（1.5和3T）或测量的磁场暴露无关。
普遍症状的报告与在MRI科室工作的时间较长有关，但与测量的暴露场强无关。与组织和压力相关的其他因素似乎导致MRI相关症状的报告增加。
• 从事MRI的日常工作与短暂症状报告增加有关 • 未证明与磁场强度有关。• 组织因素和压力也导致MRI相关症状的报告增加。
