“…Similarly, de Wilde et al reported a case of hearing loss accompanied with severe headache and dizziness after a 0.5 Tesla MRI without hearing protection [10]. Govindaraju et al also reported a case of unilateral hearing loss and tinnitus after a 3-Tesla MRI procedure.…”

Magnetic resonance imaging (MRI) devices produce noise, which may affect patient's or operators' hearing. Some cases of hearing impairment after MRI procedure have been reported with different patterns (temporary or permanent, unilateral or bilateral, with or without other symptoms like tinnitus). In this report, a case of bilateral sensorineural hearing loss in an otherwise healthy patient underwent brain MRI was described. The patient's hearing loss was accompanied with tinnitus and was not improved after 3 months of followup.

“…Nonetheless, its prevalence appears to be high as shown in this study. Most importantly, the consequences of lone working in MRI departments have been identified as potentially catastrophic, for example, asphyxiation caused by cryogen, in spite of rare likelihood of their occurrence [9,19]. A significant risk is associated with this working situation [19].…”

“…Liquid helium used for maintaining the electromagnet of the MRI machine becomes gaseous when a magnet quench (shutdown) occurs. Some of the helium gas may replace oxygen in the scanning room leading to MR technologist's asphyxiation if the ventilation for the helium is not functioning properly [3,[6][7][8][9]. A small number of patients may present aggressive behaviors to medical imaging technologists [6,10,11].…”

Objectives: It is recommended that magnetic resonance (MR) technologists should not work alone due to potential occupational health risks although lone working is legally acceptable. The objective of this study was to investigate the current situation of lone working MR technologists in Western Australia (WA) and any issue against the regulations. Materials and Methods: A questionnaire regarding the issues of occupational health of lone working MR technologists was developed based on relevant literature and distributed to WA MR technologists. Descriptive (percentage of frequency, mean and standard deviation) and inferential statistics (Fisher's exact, Chi 2 and t tests, and analysis of variance) were used to analyze the responses of the yes/no, multiple choice and 5 pt scale questions from the returned questionnaires. Results: The questionnaire response rate was 65.6% (59/90). It was found that about half of the MR technologists (45.8%, 27/59) experienced lone working. The private magnetic resonance imaging (MRI) centers were more likely to arrange technologists to work alone (p < 0.05). The respondents expressed positive views on issues of adequacy of training and arrangement, confidence and comfort towards lone working except immediate assistance for emergency (mean: 3). Factors of existence of MRI safety officer (p < 0.05) and nature of lone working (p < 0.001-0.05) affected MR technologists' concerns. Conclusions: Lone working of MR technologists is common in WA especially in private centers. The training and arrangement provided seem to be adequate for meeting the legal requirements. However, several areas should be improved by the workplaces including enhancement on immediate emergency assistance and concern relief.

“…Thermal injuries are the most common type of incidents reported in the MR environment; and between 1990 and 2006, over 20% of the burn injuries reported to the MHRA were directly attributed to monitoring leads and electrodes. 7 To minimize the potential for thermal injury, monitor cables should be placed without loops, high-resistance cables should be used, and, where possible, the sensor and cable should be placed away from the RF coil. To further minimize the chance of thermal injury, cables should not run in direct contact with skin.…”
