CT Perfusion Timing feat. Amir Khadivi
In this AJNR Fellows' Journal Club article summary, Dr. Francis Deng and Dr. Amir Khadivi discuss the article by Proner et al., " Impact of Clinical and Radiologic Factors on CTP Timing in Acute Ischemic Stroke. " They discuss the authors' findings that cardiac arrhythmias and older age are independent predictors of nondiagnostic CTP exams. Specifically, these factors often lead to the truncation of reference vessel time-attenuation curves that fail to reach equilibrium within a 45-second acquisition window.
