Stroke is one of the main causes of death and long-term disability in the U.S. Quick diagnosis and treatment are very important. Radiology helps doctors by showing images like CT and MRI scans. These scans show the type and damage of the stroke.
Artificial intelligence (AI) tools are helping radiologists work faster by quickly processing images, sorting cases, and assisting with diagnosis. AI can find signs of bleeding in the brain, blocked blood vessels, aneurysms, and other problems that need immediate care. This helps doctors see urgent cases sooner.
Dr. Jason Talbott, a neuroradiology professor, says AI helps at many points in the imaging process, especially for stroke. AI can detect key problems like brain bleeds and vessel blockages with about 88% to 95% accuracy. This helps save time without lowering the accuracy, which is very important in stroke care. AI is very useful where radiologists have many cases and might face delays.
Many studies have shown that AI helps in neuroradiology and stroke imaging. For example, AI programs can detect abnormal brain scans like bleeds and aneurysms with high accuracy. One study showed commercial AI systems found brain bleeds, strokes, and spine fractures with 88% to 95% sensitivity.
When AI is used together with expert radiologists, diagnosis gets better. Adamchic and colleagues (2024) found AI spotted 72.6% of brain aneurysms on MRI scans while neuroradiologists found 92.5%. Using both AI and doctors cuts reading time by 23%, saving about 19 seconds per case. This saves a lot of time in busy stroke centers and lets radiologists focus on harder cases.
AI also helps reduce differences in how images are read, especially for less experienced radiologists. Studies show AI tools almost match expert-level accuracy in finding small aneurysms and slight problems that humans sometimes miss. This helps make sure patients get right treatment fast.
AI is also starting to help with risk assessment and treatment planning. Machine learning models can predict the risk of an aneurysm bursting, helping doctors make better decisions on patient care.
AI affects not only patient care but also hospital budgets. One study in a U.S. hospital using an AI radiology platform showed a 451% return on investment (ROI) over five years. The ROI grew to 791% when saving radiologists’ time was included.
This AI saved radiologists more than 15 workdays in wait time, 78 days in patient sorting, 10 days in image reading, and 41 days in report writing every year. Faster results help hospitals see more patients without lowering care quality. Also, AI helped identify follow-up scans and treatments that added extra income.
Healthcare administrators and hospital owners should think about factors like hospital type, how many scans are done, and when benefits would appear. The main reason ROI improves is because AI finds problems that lead to more treatments and procedures.
These financial gains are important because healthcare always faces pressure to cut costs while keeping quality high. AI helps hospitals show clear savings by cutting labor costs, making workflows smoother, and adding new income sources.
AI helps improve workflows in radiology by automating many office and clinical tasks. This lowers the workload on staff and lets them focus more on patient care.
In stroke care, AI can automatically sort urgent scans, mark high-risk patients, and create structured reports. Tools like GPT-4 can change free-text reports into organized templates. This makes reporting faster and keeps records clear for doctors and billing.
Deep learning reconstruction (DLR) improves image quality and makes CT and MRI scans faster. Patients spend less time in machines, which makes them more comfortable and allows more patients to be scanned each day. This leads to better operations and cost savings.
AI tools mainly work on sorting and prioritizing stroke scans. Automated systems quickly alert radiologists when they find brain bleeds or blocked vessels. This helps teams act fast. These systems keep a steady ability to spot injuries and lower missed diagnoses.
Hospitals in the U.S. using AI workflow tools can handle more patients even with fewer radiologists. To make AI work well, hospitals must validate the tools, train teams, and keep data secure.
AI in stroke radiology can help improve patient care and hospital efficiency. It does this by automating problem detection, cutting down reading time, and helping doctors treat patients quickly in a busy health system.
Financial studies show AI gives good returns when considering cost savings and more revenue from better workflows. Still, hospitals need to introduce AI carefully with focus on testing, training, and ethical use to get the best results.
Hospital leaders who want better stroke imaging should see AI as a tool for clinical help and smart investment. This can help with the growing demands on radiology in the United States.
The ROI calculator was developed to evaluate both monetary and nonmonetary benefits of adopting an AI-powered radiology diagnostic imaging platform, aiding decision makers in healthcare.
The study constructed a calculator to analyze comparative costs, estimated revenues, and quantify clinical value using expert interviews and literature review over a five-year time horizon.
The introduction of the AI platform resulted in a 451% ROI over five years, which increased to 791% when accounting for radiologist time savings.
Radiologists gained significant time savings including over 15 days of waiting time, 78 days in triage, 10 days in reading, and 41 days in reporting.
AI identified patients needing follow-up scans and treatment, increasing hospital revenue through these clinically beneficial procedures.
Results were sensitive to variables like the time horizon, health center settings, and the number of scans performed, with additional treatments being the most influential factor.
The ROI calculator serves as a valuable tool for decision makers evaluating AI-powered platforms, providing a structured way to assess potential benefits and justify investments.
The AI application was primarily focused on improving workflows in radiology, specifically in the context of stroke management within hospitals.
The effectiveness of AI was evaluated through scenario and deterministic sensitivity analyses, assessing the drivers that impact the outcome of the ROI calculator.
