Cerebral Small Vessel Disease

Pantoni L, Gorelick PB, eds. Cerebral Small Vessel Disease. Cambridge Medicine; 2014; 371 pgs; 118 illlustrations; $135.00

small-vessel-disease-coverAlthough it would seem that the topic of this book is too narrow for an entire book, it is in fact not. As all neuroradiologists know, this is a topic that is faced every day, multiple times. It is as omnipresent as degenerative disc disease.

This 360-page hardcover book, with 40 contributors and 2 editors (Drs. Pantoni and Gorelick), covers all subjects related to intracerebral small vessel disease, from clinical to pathology to radiology.

The book is divided into 4 sections, each containing … Continue reading >>

Perfusion-Based Selection for Endovascular Reperfusion Therapy in Anterior Circulation Acute Ischemic Stroke

Editor’s Choice July 2014

(2 of 3)

The authors attempted to determine if reperfusion therapy for anterior circulation acute stroke based on MR perfusion resulted in better outcomes at 3 months than that based on noncontrast CT. Perfusion imaging-selected patients had a better outcome than those selected with only noncontrast CT but MR perfusion- and CT perfusion-selected patients had similar outcomes. In this multicenter study, patients with acute stroke who underwent perfusion imaging were more than 2-fold more likely to have good outcomes following endovascular reperfusion therapy

Natural Course of Dissecting Vertebrobasilar Artery Aneurysms without Stroke

Fellows’ Journal Club July 2014

(2 of 3)

More than 100 conservatively managed nonstroke dissecting vertebrobasilar artery aneurysms were followed on average for 3 years. Ninety-seven percent of patients remained clinically unchanged and the 3 patients who deteriorated clinically had aneurysm enlargement. The natural course of these lesions suggests that acute intervention is not always required and close follow-up without antithrombotic therapy is reasonable. Patients with symptoms due to mass effect or aneurysms of >10 mm may require treatment.

Google Scholar Ranks AJNR in Top 10 Radiology and Imaging Journals

AJNR is the highest-ranked subspecialty journal (#7) in the Google Scholar Metrics List of Top Publications—Radiology and Medical Imaging. Google Scholar Metrics provide authors a way to quickly gauge the visibility and influence of recent articles in scholarly publications. Scholar Metrics summarize recent citations to many publications, assisting authors as they consider where to publish their research. Journals in the list of top publications are ordered by their 5-year H-index and H-median. Viewers can click on an H-index score to see which articles in a journal were cited the most and browse a full list of the citations.

Social Networks in Science: Past and Present [Infographic]

The infographic below, produced by labroots, summarizes changes in the way researchers and journalists have publicized scientific research over time, from traditional print channels to the social networks and electronic outlets we rely on constantly today.

Some of AJNR‘s recent efforts have been implemented in service of prompting more neuroradiologists to interact with these new information streams. Our Social Media Vignettes, we hope, will prove useful guides for curious scientists who may not know where to start with so many networks available, or who may want to know what exactly social media can do to help them … Continue reading >>

Are We Effectively Informing Patients? A Quantitative Analysis of On-Line Patient Education Resources from the American Society of Neuroradiology

Editor’s Choice July 2014

(1 of 3)

The readability of 20 patient education articles found on the ASNR Web site were evaluated using 10 quantitative readability scales and compared with those found on the Web site of the Society of Neurointerventional Surgery. The authors concluded that the patient education resources on both Web sites failed to meet the guidelines of the National Institutes of Health and American Medical Association. Members of the public may fail to fully understand these resources and would benefit from revisions that result in more comprehensible information cast in simpler language.

MRI Surrogates for Molecular Subgroups of Medulloblastoma

Fellows’ Journal Club July 2014

(1 of 3)

These authors seek to establish the imaging features that would allow classification of medulloblastomas according to their genetic attributes. In nearly 100 tumors they found that groups 3 and 4 occurred predominantly in the fourth ventricle, wingless ones were located in the cerebellar peduncles or CPA region, and sonic hedgehog tumors were present in cerebellar hemispheres. Midline group 4 tumors showed minimal contrast enhancement. Thus, tumor location and contrast-enhancement patterns may be predictive of the molecular subtypes of medulloblastoma.

ORCID Metadata Added to AJNR Articles

AJNR’s first article containing embedded ORCID metadata was published on July 17. The PDF version of this article contains an interactive icon that connects to the first author’s ORCID profile.

ajnr.A4045

The core mission of ORCID is to provide an open registry where researchers
may obtain a unique and persistent identifier that can be linked with works as they are made public. The focus is on solving the problem of how authors can get appropriate credit for their contributions if they cannot be distinguished from one another: authors may have the same name as others, their names may change over the … Continue reading >>
