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.
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 I had a SPECT-CT scan back in 2024 when I started my cancer treatment. They injected me with 99m Technetium, I had to go home and brew for a couple of hours, and OF COURSE I had to go stand by my geiger counter.
It picked me up 10m away, at 5m it was at 20000 counts per minute, at 2m 60000, then sitting on my thigh 120000cpm.
"Don't spend any time next to babies, young animals or the elderly" was the advice. OK doc!
I was still fizzing the following morning...
@NanoRaptor And to my horror I see I already replied with that.
It's the weather; it's been waaaay too hot!
