Worklist prioritization is going to be the main first use of AI. For example, Nines (
Radiologist Jobs in Top Quality Teleradiology Practice.) uses AI to prioritize scans that have intracranial hemorrhage and mass effect. The effect is so that you read that head CT with the intracranial hemorrhage in 5 minutes rather than 25 minutes after it's done. The side effect is that the other head CT that's negative or has hydrocephalus that you would have read in 25 minutes will instead be read in 30 minutes after it's done. It's going to benefit patient care in a difficult to measure way, because overall report turnaround time and length of stay won't change, just for the ones positive for the target conditions of the AI program, and imperfectly (overcalling) at that.
Another program is Viz.ai (
Viz.ai, Inc.), which is similar to worklist prioritization except it bypasses the radiologist to alert the stroke neurology team directly. I don't know how effective this is in real life. At my institution, which is a comprehensive stroke center, all stroke codes that warrant a CTA are going to be attended to immediately by a radiologist, usually at the scanner before images even make it to PACS, because the emergency medicine and the stroke neurology team that examined the patient is acting as the worklist prioritization for us by escalating to code stroke in the first place. The order of operations is stroke doctor examines patient, and then you get imaging, not the other way around.
