- Pharmaceutical and molecular data
Machine learning is one of the major technologies used in medical AI. Some systems are designed for highly specific tasks, while newer generative AI systems can work with text and multiple types of information.
The FDA describes AI as technology that can make predictions, recommendations or decisions based on human-defined objectives and notes its growing intersection with medical products.
How Does AI in Medicine Work?
A simplified medical AI workflow looks like this:
Medical Data → AI Model → Pattern Analysis → Output → Professional Review → Decision
For example, an AI system designed for medical imaging may analyze an image and identify an area that should receive additional attention.
The AI output is then reviewed within the appropriate clinical workflow.
This distinction is important because an AI prediction is not automatically the same thing as a medical diagnosis.
The FDA notes that AI-enabled medical devices can be used for applications including image processing, early disease detection, diagnosis, prognosis, risk assessment and personalized diagnostics.
15 Powerful Uses of AI in Medicine
