A new artificial intelligence tool co-developed by Singapore General Hospital (SGH) can detect brain bleeding from scans in about six minutes, instead of the 30 minutes to an hour that radiologists at the hospital need for urgent cases.
The AI model named iScreen analyses the computed tomography (CT) scans and picks up white spots which signal bleeding in the brain, and locations of bleeding which might have more severe impact on the patient.
Once the AI model flags a positive result, an SMS will be sent to both the neuroradiologist and attending doctor, said senior consultant Sarat Kumar Sanamandra, who is from the same department.
This will nudge the neuroradiologist to prioritise reviewing the AI results of that patient, ahead of all other scans in the queue.
SGH's data on 3,475 CT brain scans in November and December 2025 showed that the sensitivity of iScreen is 93.1 percent.
The hospital's data also showed that the proportion of bleeding cases that took more than an hour to be reported dropped from 14.6 percent to 5 percent with the use of iScreen.
