Artificial intelligence in neuroradiology: brain CT perfusion imaging for acute ischemic stroke management

Recent International and National Guidelines for management of Acute Ischemic Stroke recommend the use of automated perfusion software that calculates core/penumbra maps to support clinical decision-making. Artificial intelligence (AI) algorithms requires human expertise for the interpretation and real-life implementation, challenging the Radiologist to be responsible for the performance of this new diagnostic AI-based tool. We illustrate our experience introducing an automated computed tomography brain-perfusion software in the critical setting of the Emergency Radiology of a hub hospital, showing advantages and limitations of the currently available AI technology.
