New AJNR Feature: Weekly Question and Poll

MCastillo — Fri, 28 Aug 2009 13:31:14 +0000

Starting Monday, August 31, when you visit AJNR.ORG you will find our new weekly activity: question and poll. Every Monday we will post a new question and our visitors can vote on an answer. These questions will refer to controversial aspects of neuroimaging, many which we face on a daily basis. Once you click on the answer, you should be able to see how the poll is progressing. One week later, we will post the results of the poll for all to see. We will create a repository of these questions/polls which hopefully will give us an idea as to how the Neuroradiology community thinks about some issues. Our website users are invited to submit questions they feel are appropriate and we will also post- if desired- the name of the person who contributed the question. This is just one of several exciting activities we have planned for our journal starting this Fall. Come back and visit AJNR and our blog frequently to stay current in your knowledge of Neuroradiology!

Educational presentation: Imaging of Acute Torticollis

Imaging in Acute Torticollis (NXPowerLite)

As promised, here is another educational exhibit that deals with the imaging of a common clinical problem: torticollis. As with the previous one, this was already presented at an ASNR meeting. It represents the work of several members of our division. Since the presentation is not protected, feel free to use it but please acknowledge its source. I invite all of you who have previous electronic exhibits to post them in this here.

Trigeminal Cystic Schwannomas

Marcela Posada — Tue, 23 Jun 2009 13:49:15 +0000

We present two cases of cystic lesions in the Meckel’s cave, both of which showed fluid-fluid levels on MR images and are consistent with trigeminal cystic schwannomas.

Fluid-fluid levels are the result of mucinous areas or microcysts, or as a result of necrosis and hemorrhage. The fluid is unclotted blood against serous fluid. In addition, in areas of necrosis, the fluid that fills a necrotic cavity early on tends to be more proteinaceous than newer interstitial fluid. In such cases, fluid separation, based on viscosity and protein content, may occur. When fluid levels are seen in masses arising from nerves, schwannoma should first on the differential diagnosis.

We would like to know if anyone has had a similar experience with intracranial schwannomas.

Celiac disease with brain ALS-like abnormalities

MCastillo — Thu, 05 Feb 2009 20:20:29 +0000

We just had a patient with ALS-like brain changes on FLAIR images who has celiac disease. After a 3-month period of treatment for his celiac disease, brain MRI was repeated and all previously seen abnormalities resolved. We are interested in reporting it and would like to collaborate with anyone who has a similar case. Please post a comment here or email me.

Giant Capillary Telangiectasias

anne osborn — Tue, 03 Feb 2009 18:02:36 +0000

I’m not talking about the itty bitty ones in the pons, etc…these are BIG. Like > 1cm. We have a nice case spectrum we’re putting together, including T2* (GRE, SWI) so if anyone has one or more of these, let me know and join in the fun. We’ll include you in the paper.

CNS Amyloidomas

anne osborn — Tue, 03 Feb 2009 18:01:47 +0000

We are looking for biopsy-proven cases of brain amyloidoma (NOT amyloid angiopathy!) for a paper on imaging spectrum we are putting together. Anyone got milk? If so, pls let me know and we would happily include you on the paper. Some of our cases are really wild.

Review articles in AJNR, interested?

MCastillo — Fri, 23 Jan 2009 19:44:23 +0000

We strive to publish 2-3 review articles in each issue of AJNR. Two of them are generally related to clinical/medical neuroradiology while one is deals with the physics pertaining to the imaging techniques that we currently employ or will soon become available. In addition, occasionally we have articles appearing under the heading of ‘research perspectives’. The latter are intended to provide our readers with a glimpse into the future of neuroradiology by commenting on activities/topics that at this point in time are at the research stage and to guide future research. Obviously, publishing over 30 of such articles every year requires enormous contributions from neuroradiologists. If you (or someone you know) are interested in writing one of these articles, please contact me directly. We have several review articles in the preparatory stage and would like to avoid duplication of topics.

Editor-in-Chief: Welcome to our Blog Site

MCastillo — Thu, 22 Jan 2009 18:31:04 +0000

We continue to work on creating a website that has all of the features that our readers want. To bring more Web 2.0 capabilities to it we now introduce our blog site. Comments may be posted after filling out an easy registration form. Comments will carry the name and institution of their author, and if that person wishes, his or her picture. Comments will be held for a short period of time before final posting. During this period of time they will be reviewed and those that carry inappropriate content and/or language will be deleted. Dr. Robert Quencer, former EIC of AJNR, has agreed to serve as our initial moderator and will screen all messages before their postings. Please follow the instructions or contact Karen Halm or Jason Gantenberg at the Main Office if you need help.

It is my wish that all of our authors, readers and the public in general participate in this interactive feature. With time, this blog site will replace our section of Letters to the Editor. Posting comments on articles previously published provides some post peer review evaluations and will help keep them updated and fresh as authors respond to questions and even add information. Authors of articles being commented upon will be contacted so that they may respond.

I suggest keeping the tone of all messages informal. Utilize this site as a way to ‘chat’ with your colleagues regarding issues pertaining to AJNR, neuroradiology in general, problem cases and to foster collaborations in general. Although other journals have had a mixed experience with their blog sites, we neuroradiologists have strong opinions and like to be heard. Because of this I am certain that our blog site will be a success!
