“…The baseline questionnaire included questions about transient effects (Bsubjective symptoms^) that have previously (ever) been associated with being in the vicinity of MRI systems [6][7][8], and although not exclusively caused by exposure to the magnetic fields from MRI they are termed 'MRI-related symptoms' for the purpose of these analyses. In addition, subjective reference symptoms from the Lund Subjective Health Complaint Inventory (SHC) questionnaire [21] experienced within the month prior to measurements were also included to evaluate whether radiographers report certain symptoms more often than, or more severe than the general population; some of which may overlap with the list of MRI-related symptoms ( Table 1).…”

“…Reported health complaints were grouped into 'MRI-related' and 'non-MRI-related' based on similar classifications in previous studies [6][7][8], and the total number of complaints reported by each participant was used as a measure of severity. Associations between the prevalence of health complaints and various exposure-related and organisational determinants were analysed using univariate and multivariate ordinal logistic regression using the MASS package in R (version 3.0.1) [27].…”

“…However, results from observational studies of MR engineers [6], healthcare and research staff [7], and MR nurses [8] have consistently shown that staff report experiencing various transient symptoms. The frequency of reported complaints was related to the strength of the MRI systems with which staff routinely worked in all studies.…”

Objectives 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. Methods 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. Results 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. Conclusions 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. Key Points • 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

A prospective randomized balanced cross-over study using a head scan in real MRI with whole-body transmitting coil and sham MRI among 24 healthy male volunteers was conducted. Serum-blood samples of inhibin B, testosterone, prolactine, thyreotropine, luteinizing hormone, follicle stimulating hormone, sex-hormone binding globuline and estradiol were taken before and after the different scans. Neither immediately after, nor after 11 days were there seen any differences in the hormone levels comparing real and sham MRI. The lack of effects of EMF on male reproductive hormones should be reassuring to the public and especially for men examined in MRI. Adverse effects on other endpoints than male reproduction or possible chronic effect of multiple MRI scans have not been investigated in this study. Abstract (150 words)The use of mMagnetic resonance imaging (MRI) is increasing around the world and the possible adverse effects on reproductive health of electromagnetic fields (EMF) in MRI are not previously studied. We conducted aA prospective randomized balanced cross-over study using a head scan in real MRI with whole-body transmitting coil and sham MRI scan among 24 healthy male volunteers was conducted.
