New AJNR Feature: Weekly Question and Poll
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 … Continue reading >>
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.… Continue reading >>
Trigeminal Cystic Schwannomas
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 … Continue reading >>
Celiac Disease with Brain ALS-like Abnormalities
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.… Continue reading >>

Review Articles in AJNR, Interested?
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 … Continue reading >>
