When we talk about AI in healthcare, people often mix up two important concepts - AI models and AI applications. But they're actually quite different!
Think of it like medical equipment: a diagnostic algorithm is powerful, but you need the complete system to actually help patients.

Can you guess which part AI models are like?
An AI model is the "brain" or "diagnostic engine" - it's the mathematical core that's been trained on medical data to recognize patterns or make predictions.
Models like those trained to detect cancer in CT scans are just algorithms with learned parameters. They're pure intelligence without a way to interact with clinicians.
Engagement Message
What would a diagnostic algorithm be without a complete medical system?
An AI application (or system) is the complete package - it takes that model and wraps it with everything needed to make it clinically useful.
This includes the user interface for doctors, patient data integration, reporting tools, and all the infrastructure that lets clinicians actually use the AI.

Starting to see why a radiology AI system is more than just the detection model?
A radiology AI system is the application - it provides the clinical interface, integrates with PACS systems, manages patient data securely, and handles regulatory compliance.
Inside, it uses AI models as its "engine" to analyze medical images. But without the application layer, the AI model would just be code that can't help any patients!
Engagement Message
What other parts might a healthcare AI application need?
Healthcare AI applications typically include HIPAA-compliant data handling, EHR integration, clinical workflow tools, audit trails, and patient safety monitoring.
Think of a clinical decision support system - the prediction algorithm is the "model," but the app includes patient records, alerts, treatment recommendations, and much more!
