Utility of the K-Means Clustering Algorithm in Differentiating Apparent Diffusion Coefficient Values of Benign and Malignant Neck Pathologies• A. Srinivasan, C.J. Galbán, T.D. Johnson, T.L. Chenevert, B.D. Ross, and S.K. Mukherji
What is K-means clustering? It is a statistical technique that allows one to cluster or classify objects according to a common trait. In this study, the authors used this technique in an attempt to classify neck lesions as either benign or malignant according to their ADC values. The reason for this: using isolated ADC values for this same purpose is fraught with difficulty and not always reliable. … Continue reading >>

Occurrence and Predictors of Futile Recanalization Following Endovascular Treatment among Patients with Acute Ischemic Stroke: A Multicenter Study • H.M. Hussein, A.L. Georgiadis, G. Vazquez, J.T. Miley, M.Z. Memon, Y.M. Mohammad, G.A. Christoforidis, N. Tariq, and A.I. Qureshi
Despite the fact that arterial recanalization is the principal goal of endovascular treatment in acute stroke patients many fail to get clinically better. Why? This is the question addressed by these investigators who basically analyzed the existing literature in this topic. Patients received pharmacological and/or mechanical thrombectomies. The authors tried to establish the cause of poor clinical outcome despite complete … Continue reading >>
Clinical Neurotoxicology: Syndromes, Substances, Environments
Dobbs MR, ed. Clinical Neurotoxicology: Syndromes, Substances, Environments. SAUNDERS Elsevier 2010, 720 pages, $186.00.
In a very topical and important new 720-page text Clinical Neurotoxicology: Syndromes, Substances, Environments Michael R. Dobbs, the editor, and 65 contributors have catalogued, described, illustrated, and discussed a wide variety of substances which are toxic to the nervous system. In addition the authors devote the first 248 pages to an overview of neurotoxins, syndromes associated with neurotoxins, and the testing for neurotoxins.
The first thing one sees when opening the text are 15 pages of color plates with 2 to 4 color photographs on … Continue reading >>

The Requisites: Neuroradiology
Yousem DM, Grossman RI, eds. The Requisites: Neuroradiology. MOSBY 2010, 704 pages, $99.00.
The remarkable success of The Requisites: Neuroradiology (1st and 2nd editions) is well justified. Each in its time was generally recognized as the best source for learning and refreshing one’s knowledge in Neuroradiology. Now we have a 3rd edition, published this year (2010), with David Yousem switching places with Bob Grossman in their editorship roles.
When comparing this 3rd edition to the 2nd edition published 7 years ago, one is immediately struck by a number if things: the book is lighter, … Continue reading >>
Companion to Peripheral Neuropathy: Illustrated Cases and New Developments
James P, Dyck P, Engelstad JK, Low PA, Amrami KK, Spinner RJ, Klein CJ, eds. Companion to Peripheral Neuropathy: Illustrated Cases and New Developments. Saunders Elsevier 2010, 432 pages, $159.00.
This 432-page hard cover book, with activatable online search capability of the full text, is basically a collection of cases (predominately case reports) and short scientific reports. It is edited by Peter Dyck with 7 other co-editors and has 145 contributors, who have mainly co-authored case reports. Given that this is primarily a compendium of peripheral neuropathy, the value to the neuroradiologist will be relatively low, however there is … Continue reading >>
Bias and Language in Scientific Articles
In the last issue of JACR (J Am Coll Radiol 2010; 7: 490-494) Dr. James Brenner addresses some of the more subtle manifestations of bias in the scientific literature. These biases arise because they are generally not identified during the peer review process and because literature is often (mis)quoted by not going back and reading the original articles. Misleading data self perpetuates when this happens. I urge all of our authors to go back to original articles and read them and judge their quality and significance that way. He also writes: “The use of adverbs should have a restricted … Continue reading >>
Milosh Perovitch Travel Grant
Milosh Perovitch was a Yugoslav physician who spent several years of his academic career in the Department of Radiology at Johns Hopkins Medical Institution in the 1960’s and 1970′s. Upon his death in 2006, he made a bequest to the JHMI Neuroradiology Division who have decided, in view of Dr. Perovitch’s close ties to Europe, to offer reverse sabbaticals to Europeans willing to visit Johns Hopkins for a period one to two months. The goal of the visit will be to exchange knowledge and develop collaborations. The stipend would be used to defray the visitors’ expenses for the month as … Continue reading >>
