BACKGROUND: In addition to occipital hypoperfusion, preserved metabolism of the posterior cingulate gyri (PCG) relative to the precunei is known as the cingulate island sign (CIS) in the patients with dementia with Lewy bodies (DLB). CIS has been detected using [(18)F]fluorodeoxyglucose positron emission tomography but not using brain perfusion single-photon emission computed tomography (SPECT). The purpose of this study was to optimize brain perfusion SPECT to enable differentiation of DLB from Alzheimer's disease (AD) using CIS and occipital hypoperfusion...

Our purpose was to determine if associations exist between titles characteristics and citation numbers in Radiology, American Journal of Roentgenology (AJR), and American Journal of Neuroradiology (AJNR). This retrospective study is Institutional Review Board exempt. We searched Web of Science for all original research and review articles in Radiology, AJR, and AJNR between 2006 and 2012 and tabulated number of words in the title, presence of a colon symbol, and presence of an acronym. We used a Poisson regression model to evaluate the association between number of citations and title characteristics...

PURPOSE: The aim of this study was to compare the volume of individuals who viewed online versions of research articles in 2 peer-reviewed radiology journals and a radiology blog promoted by social media. METHODS: The authors performed a retrospective study comparing online analytic logs of research articles in the American Journal of Neuroradiology (AJNR) and the American Journal of Roentgenology (AJR) and a blog posting on from April 2013 to September 2014...

The original versions of Tables 1–4 that were contained in the article "International Retrospective Study of the Pipeline Embolization Device: A Multicenter Aneurysm Treatment Study" by D.F. Kallmes, R. Hanel, D. Lopes et al (AJNRAmJ Neuroradiol 2015;36:108–15, originally published on-line on October 29, 2014, 10.3174/ajnr.A4111) contained errors. Due to a coding problem, 36 PICA and vertebral artery aneurysms were changed from "anterior" to "posterior." In addition, 17 ICA aneurysms were changed from "other anterior" to "ICA...

BACKGROUND AND PURPOSE: Self-plagiarism is a form of research misconduct that can dilute the credibility and reputation of a scientific journal, as well as the represented specialty. Journal editors are aware of this problem when reviewing submissions and use on-line plagiarism-analysis programs to facilitate detection. The American Journal of Neuroradiology (AJNR) uses iThenticate to screen several submitted original research manuscripts selected for review per issue and retrospectively assesses 3 issues per year...

Quantitative, qualitative, and innovative application of bibliometric research performance indicators to anatomy and radiology research and education can enhance cross-fertilization between the two disciplines. We aim to use these indicators to identify long-term trends in dissemination of publications in neuroimaging anatomy (including both productivity and citation rates), which has subjectively waned in prestige during recent years. We examined publications over the last 40 years in two neuroradiological journals, AJNR and Neuroradiology, and selected and categorized all neuroimaging anatomy research articles according to theme and type...

PURPOSE: Interventional C-arm CT imaging, today, plays an important role in the diagnosis and treatment of patients. The main part of the 3D imaging techniques, currently used in interventions, are morphological imaging techniques. So far, the ability for functional or perfusion imaging is limited, e.g., only static cerebral blood volume measurement [A. S. Ahmed, Y. Deuerling-Zheng, C. M. Strother, K. A. Pulfer, M. Zellerhoff, T. Redel, K. Royalty, D. Consigny, M. J. Lindstrom, and D...

Choristomas of the internal auditory meatus are exceedingly rare tumors. In most cases, neuromuscular choristomas have initially been misdiagnosed as vestibular schwannomas (VS). No known characteristics in the clinical presentation or in imaging exist distinguishing these tumors from VS, which are the most common tumors at this location [Smith et al.: AJNR Am J Neuroradiol 1997;18:327-329]. We present a case of a neuromuscular choristoma of the 8th cranial nerve that was operated because of growth demonstrated on two MRI scans 3 months apart...

BACKGROUND AND PURPOSE: Assessment of postpublication errors in peer-reviewed journals is difficult and the numbers and types are unknown. We reviewed published errata in major clinical imaging journals in an attempt to understand the numbers and sources of errors in published articles. MATERIALS AND METHODS: Five clinical imaging journals with the highest IFs were searched on-line using the terms "erratum" or "errata" anywhere in the title, abstract, or author listing for a total of 5 years...

The voluminous bill known as the PPACA of 2010 enabled substantial changes to our health care delivery system, some of which remain to be enacted for several years to come. While the overarching goal is to align incentives and improve quality and access, implementing PPACA initiatives in a highly complex environment is fraught with economic and political implications. The purpose of this and future AJNR Health Care Vignettes is to provide relevant updated information as it becomes available.

The purpose of this study was to determine the usefulness of perfusion CT (PCT) parameters particularly blood volume and neovascular permeability estimates (permeability surface area-product, PS) in the evaluation of oligodendrogliomas (OG), correlation with genetic subtypes of OGs (with or without loss of heterozygosity/LOH on 1p/19q) as well as comparison of perfusion parameters of OGs with astroglial tumors. Pre-operative PCT done in 21 patients with OGs was retrospectively correlated with our previously published PCT data for 32 patients with astroglial neoplasms (Jain R et al...
