After the scan, it usually takes days to hear back from a doctor. However, researchers at the University of Michigan have developed a new AI model, called Prima, that can read these scans and offer a diagnosis in just a few seconds.<\/p>\n<p data-path-to-node=\"1\">In a recent study published in <a href=\"https:\/\/www.nature.com\/articles\/s41551-025-01608-0\" target=\"_blank\" rel=\"noopener nofollow\">Nature Biomedical Engineering<\/a>, the team found that Prima was up to 97.5% accurate. Additionally, it figured out which patients needed help the fastest.<\/p>\n<p data-path-to-node=\"2\">\u201cAs the global demand for MRI rises and places significant strain our physicians and health systems, our AI model has potential to reduce burden by improving diagnosis and treatment with fast, accurate information,\u201d said Dr. Todd Hollon, a neurosurgeon at U-M Health.<\/p>\n<p>Faster MRI Results<br \/>\n<img loading=\"lazy\" decoding=\"async\" title=\"MRI machine\" alt=\"MRI machine \" width=\"1920\" height=\"1080\"  src=\"https:\/\/www.newsbeep.com\/au\/wp-content\/uploads\/2026\/02\/MRI-.png\" data- class=\"wp-image-49867 size-full lazyload\"\/>MRI machine; Photo: Marko Aliaksandr\/Shutterstock<\/p>\n<p data-path-to-node=\"4\">Most medical AI is trained to do one specific thing, like looking for a single type of <a href=\"https:\/\/www.tomorrowsworldtoday.com\/robotics\/autonomous-micro-bubble-bot-drug-delivery-targets-tumors\/\" rel=\"nofollow noopener\" target=\"_blank\">tumor<\/a>. Prima is different. The team trained it on every MRI taken at the University of Michigan since they started using digital records decades ago, that\u2019s over 200,000 studies.<\/p>\n<p data-path-to-node=\"5\">The system also looks at a patient\u2019s medical history to understand why the scan was ordered in the first place. This helps it act less like a basic calculator and more like a specialist.<\/p>\n<p data-path-to-node=\"6\">\u201cPrima works like a radiologist by integrating information regarding the patient\u2019s medical history and imaging data to produce a comprehensive understanding of their health,\u201d <a href=\"https:\/\/www.eurekalert.org\/news-releases\/1115393\" target=\"_blank\" rel=\"noopener nofollow\">explained Samir Harake<\/a>, a data scientist at the university. \u201cThis enables better performance across a broad range of prediction tasks.\u201d<\/p>\n<p>A Co-Pilot For Doctors<\/p>\n<p data-path-to-node=\"8\">When the AI spots something urgent, like a stroke or a brain bleed, it can instantly alert the right specialist.<\/p>\n<p data-path-to-node=\"9\">\u201cAccuracy is paramount when reading a brain MRI, but quick turnaround times are critical for timely diagnosis and improved outcomes,\u201d said Yiwei Lyu, a postdoctoral fellow at U-M. \u201cAt key steps in the process, our results show how Prima can improve workflows and streamline clinical care without abandoning accuracy.\u201d<\/p>\n<p data-path-to-node=\"10\">The team hopes to eventually use this technology for other scans, like X-rays and ultrasounds. Dr. Hollon said, \u201cPrima aims to be a co-pilot for interpreting medical imaging studies.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"Getting a brain MRI can be a nerve-wracking experience, mostly because of the wait.
