The present study investigated the effects of 902.4 MHz global system for mobile communications (GSM) mobile phone radiation on cerebral blood flow using positron emission tomography (PET) with the (15) O-water tracer. Fifteen young, healthy, right-handed male subjects were exposed to phone radiation from three different locations (left ear, right ear, forehead) and to sham exposure to test for possible exposure effects on brain regions close to the exposure source. Whole-brain [¹⁵O]H₂O-PET images were acquired 12 times, 3 for each condition, in a counterbalanced order. Subjects were exposed for 5 min in each scan while performing a simple visual vigilance task. Temperature was also measured in the head region (forehead, eyes, cheeks, ear canals) during exposure. The exposure induced a slight temperature rise in the ear canals but did not affect brain hemodynamics and task performance. The results provided no evidence for acute effects of short-term mobile phone radiation on cerebral blood flow.
本研究使用带有（15）O-水示踪剂的正电子发射断层扫描（PET），研究了902.4兆赫兹全球移动通信系统（GSM）手机辐射对脑血流量的影响。15名年轻、健康、惯用右手的男性受试者分别在三个不同位置（左耳、右耳、前额）接受手机辐射，并接受假照射，以测试对靠近照射源的脑区可能产生的照射影响。全脑[¹⁵O]H₂O-PET图像共采集12次，每种情况采集3次，采用平衡顺序。在每次扫描中，受试者在执行简单视觉警觉任务的同时接受5分钟照射。照射期间还对头区（前额、眼睛、脸颊、耳道）进行了温度测量。照射导致耳道温度略有升高，但未影响脑血流动力学和任务表现。结果没有提供短期手机辐射对脑血流量产生急性影响的证据。
