White Matter Tract Section
I have been asked by several invididuals to place more emphasis on articles that relate to the functional aspects of neuroimaging. One of these topics are the the white matter tracts. Starting later this year, AJNR will carry a bimonthly feature on the white matter tracts. Drs. Naidich and Fatterpekar from the Mount Sinai Hospital in NYC will be in charge of this feature. These short contributions will describe not only the anatomy of specific tracts, their DTI appearance but also their functional connections and the clinical symptoms produced when they are injured. I look forward to their contributions which … Continue reading >>
Fellow’s Journal Club Choices
For every new issue of AJNR (there are 10 per year) I generally chose 3 articles that I think offer something interesting and different to our fellows and readers in general. By clicking on the Fellow’s Journal Club tab on our website you will find the name of these articles, a short summary (all summaries will eventually be posted in this blog site) and direct links to their full text versions. Hopefully these articles will stimulate conversation between fellows and their attendings.… Continue reading >>

Cases of the Week
The case of the week feature is very popular. We now have over 18 months of cases accumulated. Every week, more than 5000 individuals (at times as close to 8000!) look at them. The database can be searched by diagnosis and or blindly by date of posting. The cases are illustrative and their degree of difficulty varies making them interesting for individuals with all levels of knowledge in neuroradiology. It is my desire, that residents and fellows will used them to study. Submissions are open only to fellows in Neuroradiology. Since AJNR and other journals accept very few case reports, … Continue reading >>
Special Collections Issues
Our first special collection issue, edited by Dr. Schaefer and Gonzalez from the MGH has been a success. You can look at it by clicking the right hand column on our website. We continue with this service and our second issue is currently being prepared. The editor will be Dr. Colin Derdeyn from the Mallinckrodt Institute. Its topic is arterial and venous recanalization which I think will nicely complement the first issue which was on imaging of stroke and its consequences. We have it planned for April of this year so come back and visit our website often! Special collections … Continue reading >>
Diet-Induced Wernicke’s
A nice article in AJNR 2009; 30: 171 shows that the brain lesions, mostly seen on FLAIR images, are different between patients with Wernicke’s induced by alcohol than that due to dietary restrictions. The abnormalities tend to be more severe in the latter. I recently saw a case that also showed involvement of the cranial nerve nuclei in the midbrain and high signal in the amygdalae. Although the article that I am mentioning here did show brainstem lesions, no lesions in the mesial temporal lobes were seen in any patients. I wonder if perhaps, hypoglycemia is also present in these … Continue reading >>
Regarding Pontine Tegmental Cap Dysplasia
There is a very nice article on this very uncommon malformation in AJNR 2009; 30: 113. We have only seen it in patients being screened for congenital sensorineural hearing loss. In these patients, its severity varies. In the above mentioned article, 4 of 6 patients had cranial nerve VIII abnormalities. I would be interested in learning from other neuroradiologists who are familar with the malformation what their experience has been.… Continue reading >>
