The Journal of Nuclear Medicine Impact Factor Increases

June 20, 2017

RESTON, Va. - The Journal of Nuclear Medicine (JNM)—the flagship publication of the Society of Nuclear Medicine and Molecular Imaging (SNMMI)—has again been ranked among the top medical imaging journals worldwide, according to new data released in the 2016 Journal Citation Reports© published by Thomson Reuters.

JNM’s impact factor went up from 5.849 (2015) to 6.646 (2016), and the journal ranked fifth in impact factor of the 125 journals included in the medical imaging category. JNM’s five-year impact factor is 6.459, up from 5.795 the previous year. Citations to the journal increased to 24,977 from 22,728, and JNM’s article influence score is 1.84.

JNM’s increasing impact factor demonstrates the journal’s influential role in molecular imaging,” said Editor-in-Chief Johannes Czernin, MD, professor of molecular and medical pharmacology and chief of the Ahmanson Translational Imaging Division at the UCLA David Geffen School of Medicine, Los Angeles, California. “Among nuclear medicine journals, JNM remains the journal with the highest number of citations, the highest average 5-year impact factor, the highest number of citable articles, and the highest influence score.” He added, “We are pleased that it is the journal of choice for many distinguished researchers, and we will continue to focus on providing the highest quality in basic, translational and clinical sciences.”

The Institute for Scientific Information (ISI) measures a journal’s impact—or significance—based on the number of article citations compared to the total number of articles published. The impact factor—a quantitative measure of the frequency with which an article in a journal is cited—is used to gauge the overall influence of a journal within scientific, professional and academic communities. For more than 50 years, Thompson Reuters’ ISI has provided a systematic and objective way for librarians, researchers and other decision-makers to measure influence in the global research community.

The Journal Citation Report also publishes an immediacy index for journals as an indicator of the speed with which citations to a specific journal appear in published literature. JNM’s immediacy index for 2016 is 1.574, up from 1.147.
