Core Tip

Core Tip: Shukun CerebralDoc system is a Chinese artificial intelligence (AI) post-processing software for computed tomography angiography (CTA) and cerebral perfusion. It is currently the most widely used vascular post-processing AI software in hospitals in mainland China. There is still a lack of relevant laws or regulations in China regarding the clinical application of AI. We found that Shukun AI computed tomography (CT) perfusion imaging has certain limitations in assessing the ischemic penumbra with an inaccuracy rate of 13.6%. We highlight that comprehensive evaluation of the ischemic penumbra in combination with the clinical symptoms, signs, and imaging findings (CT, CTA, and even magnetic resonance imaging), rather than totally relying on AI results, is a key imperative prior to decision-making for mechanical thrombectomy.
