Immune reconstitution inflammatory syndrome (IRIS) is a clinical deterioration that occurs despite increasing CD4+ T-lymphocyte counts and decreasing plasma human immunodeficiency virus-1 (HIV-1) viral loads. It results from an inflammatory response or “dysregulation” of the immune system to both intact subclinical pathogens and residual antigens. Resulting … Continue reading >>

Feasibility of Angiographic CT in Peri-Interventional Diagnostic Imaging: A Comparative Study with Multidetector CT • M.-N. Psychogios, J.-H. Buhk, P. Schramm, A. Xyda, A. Mohr, and M. Knauth
Today, many interventional neuroradiologists work with angiographic equipment that is also capable of obtaining CT images, clearly something advantageous when hemorrhages or other complications are suspected during or immediately after a procedure. In this study, the authors compared the results of angiographic CT with those of multidetector CT in 84 patients (postaneurysm coiling, -thrombectomy, or -angioplasty with stent deployment). Both CT methods rated equally in the detection of supratentorial complications … Continue reading >>

Open letter in response to NYT article from July 31, 2010 “The Radiation Boom After Stroke Scans, Patients Face Serious Health Risks” By WALT BOGDANICH
posted by Michael H. Lev and Max Wintermark
Every year in the United States, more than three quarters of a million people have a stroke, and approximately every 3 minutes someone dies from a stroke. A significant portion of stroke victims are young, and left with a devastating handicap for the rest of their lives. The monetary and societal costs of stroke represent a major economic challenge to the healthcare system. With stroke – as with heart attack – rapid treatment is essential to limit the extent of irreversible brain injury (“time-is-brain”), and rapid determination of the cause and degree … Continue reading >>
