Abstract

Despite its widespread acceptance in the scientific world, impact
factor (IF) has been criticized recently on many accounts:
including lack of quality assessment of the citations, influence
of self citation, English language bias, etc. In the current study,
we evaluated three indices of journal scientific impact: (IF),
Eigenfactor Score (ES), and SCImago Journal rank indicator
(SJR) of nuclear medicine journals. Overall 13 nuclear medicine
journals are indexed in ISI and SCOPUS and 7 in SCOPUS
only. Self citations, Citations to non-English articles, citations
to non-citable items and citations to review articles contribute
to IFs of some journals very prominently, which can be better
detected by ES and SJR to some extent. Considering all three
indices while judging quality of the nuclear medicine journals
would be a better strategy due to several shortcomings of IF.
