%X Introduction: In the current study, we compared the h-indices of Web of Science (WOS), SCOPUS, and GS of the Iranian nuclear medicine scientists Methods: Full time members of two major nuclear medicine research centers of Iran with more than 5 year of experience (Nuclear Medicine Research Center of Mashhad University of Medical Sciences, and Research Institute for Nuclear Medicine of Tehran University of Medical Sciences) were included for h-index evaluation. H-indices of SCOPUS, WOS and GS were retrieved using their specific websites. Correlations of h-indices with each other were evaluated using spearman correlation coefficient. Results: Overall 11 researchers were included in the study. SCOPUS, WOS, and GS provided somehow different h-indices for each researcher. Spearman's correlation coefficients between different h-indices were high: 0.834, 0.817, 0.857 between SCOPUS and WOS, SCOPUS and GS, and GS and WOS respectively. Rankings of researchers according to different database however, were acceptably identical.Conclusion: H-indices provided by SCOPUS, Web of Science WOS, and Google Scholar (GS) for Iranian nuclear medicine researchers can be used interchangeably. However these h-indices can be different according to which database is used. Setting up ˇ°ReasercherIDˇ± in WOS and ˇ°User profileˇ± in GS, as well as giving regular feedback to SCOPUS managers can increase the accuracy of h-indices calculation.
