The Journal of Nuclear Medicine Impact Factor Increases by 12 Percent

July 18, 2018

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 just released in the 2017 Journal Citation Reports© published by Clarivate Analytics.

JNM’s impact factor increased 12%, from 6.646 (2016) to 7.439 (2017), and the journal ranked fifth in impact factor of the 128 journals included in the medical imaging category. JNM’s five-year impact factor is 6.893, up from 6.459 the previous year. Citations to the journal increased from 24,977 to 27,101, and JNM’s article influence score is 1.852.

JNM’s increasing impact factor demonstrates the journal’s influential role in molecular imaging, and we are honored that it is the journal of choice for many distinguished researchers,” 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 continues to have the highest number of citations, the highest average 5-year impact factor, the highest number of citable articles, and the highest influence score.”

He pointed out, “As this impact factor is based on 2016 data, all the credit for this increase goes to JNM Immediate Past Editor Dominique Delbeke, MD, PhD, at Vanderbilt University Medical Center in Nashville, Tennessee. We are continuing to build on her success, focusing on providing the highest quality in basic, translational and clinical sciences.”

The Institute for Scientific Information (ISI), now based in Clarivate Analytics’ Scientific and Academic Research Group, 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, 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 2017 is 2.474, up from 1.574.
