Interventional Neuroradiology
This year, Interventional Neuroradiology will be published in the traditional printed hard copy format and also in a digital edition available on the Internet. This move will allow our readers to exploit the myriad opportunities digital medium has to offer, especially for a journal with an international readership. The subscription price will be lower in view of cost savings resulting from the digital format. The digital subscription will offer readers the leaf through format on-line, the PDF to download and print, and bibliography search with access to a dynamic articles archive. We are convinced that the digital format will further … Continue reading >>
How to report Transient Splenial Lesion and How Often to Follow It Up?
A 39-year-old man with history of tingling sensation on the left half of Face.
MRI revealed a solitary lesion in the splenium of the corpus callosum, hyperintense on T2/FLAIR and hypointense on T1W images. There is diffusion restriction.
This lesion was presumed demyelinating in view of h/o upper respiratory tract infection. At 6-week follow up MRI the lesion resolved completely.
Various etiologies have been reported for transient splenial lesions like:
- Seizures
- Sudden withdrawal of antiepileptic drugs
- Brain infarction
- Multiple sclerosis
- Cerebral trauma
- Neoplasm
- Adrenoleukodystrophy
- AIDS dementia complex
- Infections like influenza, measles, herpes, Salmonella, mumps, adenovirus, varicella zoster, Legionnaires disease,

AJNR Blog for iPhone
This blogsite is now available on a special platform (WPtouch) for iPhone. Once you access AJNRBLOG.ORG, your iPhone should default into the mobile mode automatically (if not, you can manually change it at the bottom of the screen). For those using other devices, such as a Blackberry, our standard platform should continue to be satisfactory. The new platform should also work well with devices that are android-based. Please note that our iPhone application does not support “pinching and stretching” but despite this the text is clearly readable and the illustrations are of high quality.
SIH (Spontaneous intracranial hypotension). Why should we ban “CSF hypovolemia” ? Because it’s a misnomer
Spontaneous intracranial hypotension (SIH) is now a fairly well known syndrome. Leakage of CSF is considered the pathogenetic factor, even in cases in which it is not demonstrated.
The loss of CSF volume explains the usual complaint of orthostatic headache, relieved by lying down, and the characteristic MRI findings: 1) thickening of the dura, enhancing after contrast medium administration, 2) subdural fluid collections, 3) sagging of the brain, 4) dilatation of the venous structures, which includes enlargement of the dural sinuses and veins, enlargement of the pituitary gland, and, in the spinal canal, engorgement of the epidural plexuses. All these … Continue reading >>

CT perfusion for stroke: 2 questions
1. I have read that it is OK to do the CT Perfusion study either before or after the CTA (AJNR Am J Neuroradiol 2008 29: e23-e30). I have always done the CTA first, but I would like to know what other people are doing, and what the relevant considerations are.
2. Is 80 the optimal kVp for the perfusion study?
Thanks… Continue reading >>
