Intracerebral haemorrhage (ICH) is associated with high early mortality and morbidity. Early clinical deterioration is common and influenced by haematoma expansion, which can occur within the first hours after symptom onset. Transcranial duplex sonography (TCD) is a rapid, non-invasive tool that may aid in early ICH detection but is highly operator-dependent. Artificial intelligence (AI)-based analysis of ultrasound images has shown promise in other fields but has not yet been validated in acute ICH.
