Artificial intelligence in medical imaging: From task-specific models to large-scale foundation models.

Summary: Imagine a doctor’s assistant that doesn’t just specialize in one thing, like spotting a broken bone, but understands the entire landscape of medical imagery. That is the promise of the new wave of Artificial Intelligence called "Foundation Models." While current AI tools are excellent at specific tasks—like finding a tumor in an MRI—they are limited to that single job. Foundation Models are different; they learn from vast amounts of data to handle multiple types of medical challenges, adapting quickly to new problems without needing to be retrained from scratch. The experts conclude that these new smart models won't replace the current tools but will work alongside them, acting as a powerful upgrade to make medical diagnosis faster, more accurate, and more comprehensive for everyone.
