You may have heard of a "PET scan" used in medicine. This uses a type of antimatter called a positron.

The complexity behind this is fascinating.

Just wait until you find out about MRI :)

That's pretty awesome too, but they don't need molecules with atoms that were modified using particle colliders just minutes/hours before you need them.

Still much more complex than PET conceptually, and much more versatile.
