Abstract

Positron emission tomography (PET) was used with ^18^fluorodeoxyglucose to see if gender differences in resting cerebral glucose utilization could be detected. Thirty‐two healthy subjects (15 women and 17 men; age range: 21–38 yr) were examined using a high‐resolution PET scanner to determine the regional cerebral metabolic rate for glucose (CMRglc) in 65 gray matter regions of interest. Whole brain CMRglc did not differ significantly between the two genders, nor did any of the regional CMRglc values. Only 1 of 65 ratios of regional‐to‐whole brain CMRglc differed significantly between men and women, which is consistent with chance. These results indicate that there are no differences in resting regional cerebral glucose utilization between young men and women.
