Proton magnetic resonance spectroscopy (1H MRS) was used to evaluate changes in cerebral metabolites for 21 extensive users (average use = 5.5 2.2 years at 2.4 1.1 hours/day) of a mobile phone and 15 nonusers. Data were recorded in both the exposed right temporal area and the contralateral left temporal area as well as in the pontobulbar area. No statistically significant changes could be measured for the NAA/Cr, Cho/Cr and mI/Cr ratios between mobile phone users and nonusers subjects and between the exposed and contralateral temporal areas.
