Automated computed tomography (CT) perfusion in the assessment of the ischaemic core in wake-up strokes: is it reliable?

The authors aimed to evaluate the reliability of computed tomography perfusion (CTP) in assessing the ischaemic core in patients with wake-up strokes. Their findings indicate that CTP alone is not a reliable method, as it underestimated the ischaemic core in 38% of cases compared to non-contrast CT, suggesting that both imaging techniques should be used together to accurately determine thrombectomy eligibility in this patient population.
