Journal of Nuclear Medicine Impact Factor Increases

June 25, 2015

Reston, Va. (June 25, 2015)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 2014 Journal Citation Reports© published by Thomson Reuters.

JNM earned an impact factor of 6.160—an increase of more than half a point—placing higher than other prominent journals in this category. JNM ranked fourth in impact factor of the 125 journals included in the medical imaging category.

“JNM’s increasing impact factor is a testament to its influential role in molecular imaging,” said Editor-in-Chief Dominique Delbeke, MD, PhD, professor of radiology and radiological sciences at Vanderbilt University School of Medicine in Nashville, Tenn. “We are pleased that JNM continues to be the journal of choice for many distinguished researchers.”

The Thomson Reuters 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 2014 is 1.208—a 14% increase over the previous year. The total number of JNM citations (22,620) also increased, up more than 6% over the previous year.
