AJNR Special Collections now available in print!
We now have print on demand capabilities. After our first Special Collection was published online about 6 months ago we received several requests from individuals wanting print copies of it. Now, on the welcome page of each collection users will find a link that takes them to this exclusive service. For $50.00 US you can order a printed issue of all of the contents in each collection. The printed issue arrives in few days later by mail and has a nice glossy cover (similar to AJNR). The cover design changes with each issue. This a great opportunity to have in … Continue reading >>
Two Arachnoid Cysts?
I would like to have a feedback from NeuroSeniors about what could be this finding:
this is a 48 yo woman who had radiotherapy for left trigeminal neuralgia (look the temporal lobe). No pituitary gland problems.
It is evident the slit like appearance of the gland that appears something like squeezed by two cystic symmetrical formations.
Are them arachnoid cysts?
Is this a pattern already seen?
Thanks, Eytan

ASL Perfusion in Cortical Dysplasia
Arterial spin labeling perfusion is becoming an important clinical tool. We find it particularly useful in children in whom it is difficult to obtain contrast enhanced MR perfusion due to the smaller size of needles used. Here is a case of a balloon cell type cortical dysplasia in the right temporoparietal region 
with low cerebral blood flow on the ASL study. I think that our Blogsite is the ideal place to share these cases with the rest of the Neuroradiology community. Similar findings to the ones shown here were reported in the following article found in the publication preview section … Continue reading >>
AJNR Paper Points to Future of Severe Ischemic Stroke Treatment
Acute ischemic stroke remains the most important neurologic malady in the world. Severe strokes caused by artery occlusion are a minority of all strokes, but cause most of the poor outcomes and costs associated with stroke. Neurointerventionalists have effective therapies, but too few stroke patients undergo endovascular procedures. The reasons are multiple, but a major reason is that patients too frequently arrive beyond the traditional time windows for treatment. A way to break out of this dilemma is described in the paper recently ePublished in the AJNR (N. Janjua, A. El-Gengaihy, J. Pile-Spellman, and A.I. Qureshi Late Endovascular Revascularization in Acute Ischemic … Continue reading >>
Education
As a program director I would be interested in a category on education. Hopefully others are as well. Some suggested discussion topics:
It would be great if the ASNR opened up on-line content to residents.
ASNR should consider offering member in training to residents.
Programs are required to have a core curriculum of about 10 lectures. What should be the role of ASNR to help its members acheive this goal.?… Continue reading >>

Editor’s and Fellows’ Journal Club Choices, February 2009
Editor’s Choices
Cold thyroid nodules are not uncommonly found in nuclear scans. Because they have up to a 20% rate of malignancy, most have to be biopsied or excised. In this article, the authors used quantitative diffusion-weighted imaging to further characterize cold nodules as benign or malignant. They found apparent diffusion coefficient values differed significantly between carcinoma, adenoma, and normal tissue and concluded DWI is … Continue reading >>

RE: DWI for Head and Neck Lesions – Acute Ischemic Optic Neuropathy
Here’s another case for the value of DWI for head and neck lesions.
This patient had left central retinal artery occlusion and acute ischemic optic neuropathy. There is restricted diffusion in the anterior left optic nerve which is much more obvious than the mild perineural enhancement on coronal postcontrast images.
