Summary
Brainomix e-Stroke software offers rapid CT imaging analysis for acute stroke, demonstrating high accuracy in identifying hemorrhage and large vessel occlusions. It serves as a valuable adjunct to expert interpretation for stroke diagnosis.
Area of Science:
- Neurology
- Medical Imaging
- Artificial Intelligence
Background:
- Acute stroke diagnosis relies heavily on timely interpretation of CT imaging.
- Artificial intelligence (AI) tools like Brainomix e-Stroke aim to enhance diagnostic speed and accuracy.
- Real-world validation of AI decision support tools in unselected patient cohorts is crucial.
Purpose of the Study:
- To prospectively evaluate the real-world performance of the Brainomix e-Stroke AI tool.
- To assess its accuracy and reliability in interpreting CT scans for suspected acute ischaemic stroke.
- To compare its findings with established methods and expert interpretations.
Main Methods:
- Prospective evaluation of 1163 CT studies from 551 patients admitted to a hyperacute stroke unit.
- Utilized e-ASPECTS, e-CTA, and e-CTP modules of the Brainomix e-Stroke software.
- Ground truth for e-ASPECTS and e-CTA established by a neuroradiologist; e-CTP results compared with syngo.via software.
Main Results:
- e-Stroke successfully processed 97.2% of studies within an average of 4 minutes.
- High accuracy for hemorrhage detection (97.8%) and large vessel occlusions (91.5%).
- e-ASPECTS showed 77.0% accuracy for MCA territory ischemia; e-CTP volumes strongly correlated with syngo.via.
Conclusions:
- Brainomix e-Stroke provides rapid and reliable CT imaging analysis for acute stroke.
- The tool demonstrated strong performance in identifying critical stroke indicators.
- It is recommended as an adjunct to, rather than a replacement for, expert neuroradiological interpretation.
