The present study aimed to develop a method based on a standard arterial input function (SIF) to estimate input function without blood sampling. We performed\n                    <jats:sup>18<\/jats:sup>\n                    F-fluolodeoxyglucose studies accompanied by continuous blood sampling for measurement of AIF in 11 rats. Standard arterial input function was calculated by averaging AIFs from eight anesthetized rats, after normalization with body mass (BM) and injected dose (ID). Then, the individual input function was estimated using two types of SIF: (1) SIF calibrated by the individual's BM and ID (estimated individual input function, EIF\n                    <jats:sup>NS<\/jats:sup>\n                    ) and (2) SIF calibrated by a single blood sampling as proposed previously (EIF\n                    <jats:sup>1S<\/jats:sup>\n                    ). No significant differences in area under the curve (AUC) or cerebral metabolic rate for glucose (CMRGlc) were found across the AIF-, EIF\n                    <jats:sup>NS<\/jats:sup>\n                    -, and EIF\n                    <jats:sup>1S<\/jats:sup>\n                    -based methods using repeated measures analysis of variance. In the correlation analysis, AUC or CMRGlc derived from EIF\n                    <jats:sup>NS<\/jats:sup>\n                    was highly correlated with those derived from AIF and EIF\n                    <jats:sup>1S<\/jats:sup>\n                    . Preliminary comparison between AIF and EIF\n                    <jats:sup>NS<\/jats:sup>\n                    in three awake rats supported an idea that the method might be applicable to behaving animals. The present study suggests that EIF\n                    <jats:sup>NS<\/jats:sup>\n                    method might serve as a noninvasive substitute for individual AIF measurement.\n
