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 2009 is 0.956, placing it in the top three percent of medical imaging journals. At the same time, the total number of JNM citations rose to over 19,000-an increase of nearly 20 percent.
One of the most important uses of the impact factor is in the process of academic evaluation. The impact factor is often used as a measure of the quality and influence of the journals where researchers have been published. Impact factors also provide librarians with a tool to help them effectively manage journal collections and make judicious purchasing decisions. The ISI has presented quantifiable statistical data to provide a systematic, objective way to evaluate the world's leading journals and their impact and influence in the global research community for more than 45 years.
