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

Abstract

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.
