In medical technology, antimatter is used in PET scans by injecting a radioactive tracer that emits positrons; when these positrons meet electrons in the body, they annihilate and produce gamma rays that help create detailed images of tissues.

In PET scans, antimatter is used by injecting a tracer that emits positrons; when these positrons meet electrons in the body, they annihilate and produce gamma rays that create detailed images of tissues and organs.

In medical technology, antimatter is used in PET scans by injecting a radioactive tracer that emits positrons (antielectrons); when these positrons meet electrons in the body, they annihilate and produce detectable gamma rays that create detailed images of internal tissues.
