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 >>

Editor-in-Chief Mauricio Castillo Featured in NeuroNews

Mauricio Castillo

AJNR Editor-in-Chief Mauricio Castillo was featured recently in an interview with the newsletter NeuroNews. Covering the gamut from his days as a medical school student to his stint as President of ASNR, Dr. Castillo reflects on a career in neuroradiology that spans 25 years and counting—the mentors who helped lay a foundation for him as a fellow, the changing face of neuroradiology in the 21st century, and the challenges of editing a scientific publication.

In recounting his experiences, he lists his involvement with AJNR as one of the highlights of his career:

Explore the AJNR Legacy Collection

legacy-layersFounded in 1980 by Juan M. Taveras, also the founder of the American Society of Neuroradiology, AJNR became the leading neuroimaging publication in the world, and continues to be so today. But since the establishment of AJNR Online, content published prior to 1995 has not been available on the Journal‘s website. Thus, we are pleased to announce the AJNR Legacy Collection, an expansion of our archives back to the very beginning. Visitors to ajnr.org can now, for the first time, access PDFs of articles published from 1980 to the present.

After Dr. Taveras, who served from 1980–1990, AJNR has … Continue reading >>

Combined Low-Dose Contrast-Enhanced MR Angiography and Perfusion for Acute Ischemic Stroke at 3T: A More Efficient Stroke Protocol

Fellows’ Journal Club June 2014

(1 of 3)

Patients studied for acute stroke were evaluated with full- and half-dose contrast-enhanced neck MRA and brain perfusion imaging and results were compared. Detection specificity and overestimation of stenoses were slightly higher for the half-dose studies but perfusion mismatches were identified with high interobserver agreement at both doses. Thus, low-dose studies are feasible and save time and contrast volume.

Abstract

BACKGROUND AND PURPOSE
There is need to improve image acquisition speed for MR imaging in evaluation of patients with acute ischemic stroke. The purpose of this study was to evaluate the feasibility of … Continue reading >>
