There were 109 articles published in the Journal of Cardiovascular Magnetic Resonance (JCMR) in 2013, which is a
21% increase on the 90 articles published in 2012. The quality of the submissions continues to increase. The editors
are delighted to report that the 2012 JCMR Impact Factor (which is published in June 2013) has risen to 5.11, up
from 4.44 for 2011 (as published in June 2012), a 15% increase and taking us through the 5 threshold for the first
time. The 2012 impact factor means that the JCMR papers that were published in 2010 and 2011 were cited on
average 5.11 times in 2012. The impact factor undergoes natural variation according to citation rates of papers in
the 2 years following publication, and is significantly influenced by highly cited papers such as official reports.
However, the progress of the journal's impact over the last 5 years has been impressive. Our acceptance rate is
<25% and has been falling because the number of articles being submitted has been increasing. In accordance
with Open-Access publishing, the JCMR articles go on-line as they are accepted with no collating of the articles
into sections or special thematic issues. For this reason, the Editors have felt that it is useful once per calendar
year to summarize the papers for the readership into broad areas of interest or theme, so that areas of interest
can be reviewed in a single article in relation to each other and other recent JCMR articles. The papers are
presented in broad themes and set in context with related literature and previously published JCMR papers to
guide continuity of thought in the journal. We hope that you find the open-access system increases wider
reading and citation of your papers, and that you will continue to send your quality manuscripts to JCMR for
publication.
