Amir Khadivi","description":"In this AJNR Fellows' Journal Club article summary, Dr. Francis Deng and Dr. Amir Khadivi discuss the article by Proner et al., &quot;Impact of Clinical and Radiologic Factors on CTP Timing in Acute Ischemic Stroke.&quot; They discuss the authors' findings that cardiac arrhythmias and older age are independent predictors of nondiagnostic CTP exams.
