If you’ve ever had a PET scan then there was a time in your life where you shot antimatter and gamma rays from your eyes.
(Technically many other places too yes but give yourself this win)

@NanoRaptor I've had two cervical disc fusion surgeries (5 years apart), which means:
1) I have two different dead people in my neck. Supposedly there's the option of artificial shims now, but not for me. Dead guys.
2) I like to say I have more titanium in my neck than the Borg Queen.
I'll stick to bananas when I want to emit antimatter.
If it goes to my head I will eventually have a positonic brain
Issac Asimov and Star Trek 😉
@simonzerafa My PET scan was to track down if there was something particularly bad re: my migraines; twice a week for years in my 20s. Seemed a bit too awful for *just* migraines. But nope, migraines.
*definitely* had a positronic brain for a bit!
@NanoRaptor does being filled with 99m-Tc and then being SPECT-CT scanned count?
I was *fizzing* that day.
Superhero recruiter: And so, what is your superpower?
Me: I can shoot antimatter and gamma r--
Recruiter: yeah yeah gamma rays out of your eyes, great here--
Me: No, no, not out of my eyes! Out of my bellybutton!
Recruiter:
...
Next please!
I prefer to boost my antimater and gamma ray reserves by eating 🍌
Then one would be slightly heavier, yes?
@nlarson830 @NanoRaptor No, lighter!
Most of the positrons encounter electrons, anialate and emit gamma radiation which is what is actually detected in a PET scan.
It is the contrast media that emits the positions in PET.
That said, I have, rather conveniently ignored the mass of the contrast media, which would make you temporarily heavier.
@MelissaBearTrix just one here! Decades ago.
My brain is officially normal. Ish.
@NanoRaptor As luck would happen, the hospital doing the imaging cancelled on me less than an hour from when I was going to travel there. Apparently there was a delayed shipment of the radioactive material, and they didn't have enough for my test.
Frustratingly, the person who broke the news said they would reschedule me soon thereafter, but Scheduling put me a month out. I was all set mentally to soon know if I am indeed going down the path of early-onset Alzheimer's, so a month delay will be cause for rumination much longer.
