Evidence with Recent Stroke Trials: The Role of Neuroimaging – What Radiologists Need to Know (2025)-WEB02-2025

Video Transcription

Video Summary

This webinar, hosted by Dr. Achala Bagal, a neuroradiologist at the University of Cincinnati, focused on the role of neuroimaging in recent stroke trials, featuring talks by Dr. Gustavo Mendez and Dr. Vivek Yadavalli. Dr. Mendez outlined recent developments in large core ischemic stroke trials, emphasizing a shift away from exclusion based solely on core size and the importance of advanced imaging. He discussed methodologies for determining core infarct volume and highlighted significant trial findings which suggest thrombectomy can benefit a wider range of patients than previously thought. Dr. Yadavalli's session concentrated on medium vessel occlusions (MeVOs) and recent trials investigating the efficacy of endovascular thrombectomy (EVT) for MeVOs, which showed no additional benefit over best medical management. He stressed the potential utility of perfusion imaging for detecting and managing MeVOs, highlighting the need for accurate imaging criteria in future trials to identify suitable candidates for EVT. Both speakers emphasized the evolving role of imaging in optimizing stroke treatment and outlined areas for future research. The session concluded with a Q&A, discussing the practical use of CT perfusion and AI in clinical practice.
