How can AI help doctors look inside the body?
Look at real scans, guess what you see, then watch an AI describe them. At the end, check whether it got it right.
Made for students aged 11 to 14, with a presenter. It takes 15 to 20 minutes.
How a case works
Each scan comes from a real person, shared for teaching with names and personal details removed.
-
Guess first
Look at the scan. What do you think you see? Vote with a show of hands.
-
Watch the AI
It describes the scan twice: in kid words, then in doctor words. It also says what it can’t tell.
-
Check the answer
The answer key that came with the scan is revealed. Did the AI match it, partly match it, or miss?
Three ways to see inside
Doctors use different machines for different jobs. You will meet all three in the demo.
-
X-ray
It makes shadows.
Bone blocks the rays. Air doesn’t. The picture shows what got blocked. It doesn’t hurt, and doctors use only a tiny dose.
-
CT scan
It takes slices, like a loaf of bread.
A machine takes many X-rays from all around you. A computer puts them together into thin slices. It is fast, so doctors use it in emergencies.
-
MRI scan
It uses a giant magnet and radio waves.
There are no X-rays at all. The magnet switches on and off very fast, which makes the loud knocking sound. People wear ear protection.
AI is a helper. Doctors decide.
The AI in this demo is fast, and it is not always right. That is the point: you will check it against the answer key.
What the AI helper does
- Looks at a picture in seconds.
- Points to where it thinks something is, with an “about here” box.
- Says what looks normal, and what it can’t tell.
- Can miss things, or see things that aren’t there.
What the doctor does
- Talks with you and asks how you feel.
- Examines you and knows your story.
- Uses special tools that hospitals have tested.
- Checks the AI’s help, then makes the decision.
The AI’s own maker says its limits. Its company says it is not designed to interpret complex scans such as CTs or MRIs. That is why hospitals use special, tested tools, and why doctors check.
“Patchy consolidation in the right lower zone, consistent with pneumonia.”
“There’s a cloudy white patch low in the right lung. That can happen when the lung has an infection called pneumonia. Doctors can treat it.”

For teachers
The teacher guide has the learning goals, the words students will meet, a five-minute shadow-play warm-up, a 20-minute and a 10-minute plan, answers to the questions students ask, and a worksheet you can print.
It also explains in plain words what the demo does with, and without, anyone’s data. In short: no accounts, no tracking, and nothing a student says is stored.
