Fourteen healthy right-handed subjects were scanned using PET with a [15O]water tracer during exposure to electromagnetic field (EMF) emitted by a mobile phone and a sham-exposure under double-blind conditions. During scanning, the subjects performed a visual working memory task. Exposure to an active mobile phone produced a relative decrease in regional cerebral blood flow (rCBF) bilaterally in the auditory cortex but no rCBF changes were observed in the area of maximum EMF. It is possible that these remote findings were caused by the EMF emitted by the active mobile phone. A more likely interpretation of the present findings were a result of an auditory signal from the active mobile phone. Therefore, it is not reasoned to attribute this finding to the EMF emitted by the phone. Further study on human rCBF during exposure to EMF of a mobile phone is needed.
14名健康的右利手受试者在双盲条件下，于暴露于手机发出的电磁场（EMF）及假暴露期间，使用[15O]水示踪剂进行了PET扫描。在扫描过程中，受试者执行视觉工作记忆任务。暴露于处于工作状态的手机产生双侧听觉皮层局部脑血流量（rCBF）相对降低，但在最大EMF区域未观察到rCBF变化。这些远距离发现有可能是由处于工作状态的手机发出的EMF所引起。对本研究结果更有可能的解释是来自处于工作状态的手机的听觉信号所致。因此，将这一发现归因于手机发出的EMF是不合理的。需要对暴露于手机EMF期间的人体rCBF进行进一步研究。
