Radiation Dose in Neuroradiology: New Special Collection and Podcast
By now most Neuroradiologists are aware of the US Food and Drug Administration notification regarding dangerous levels of radiation exposure produced in one facility while performing CT perfusion. This unfortunate event has been front page material for the media, leading to patient anxiety and, more important, to questions regarding the use of this valuable technique. The facility involved has recently revealed that 260 patients were exposed to high radiation levels; 20% of cases involving the eyes which places these individuals at high risk for cataracts. It should come as no surprise that by the time of this writing, legal action … 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 >>
Validation and Standardization of Stroke Perfusion Methods

I encourage all who perform such imaging to participate in the “STIR” effort, being corrdinated by Max Wintermark et al at UCSF.… Continue reading >>
