Referring to PET I suppose?

PSA:

PET is a common imaging technique, a medical scintillography technique used in nuclear medicine. A radiopharmaceutical—a radioisotope attached to a drug—is injected into the body as a tracer. When the radiopharmaceutical undergoes beta plus decay, a positron is emitted, and when the positron interacts with an ordinary electron, the two particles annihilate and two gamma rays are emitted in opposite directions.^[6]^ These gamma rays are detected by two gamma cameras to form a three-dimensional image.

It fucking blew my mind when I realized what the "P" in that acronym stood for.

Wait is it fucking positron‽ Shit yeah it is.

In case anyone is confused, positrons are anti-electrons

I use the same machine for my dick pics.

Are there other antimatter imaging methods?

[–] Gust@piefed.social 21 points 3 days ago

Pedantically, I think you could call muon tomography an antimatter imaging method. It doesnt explicitly use antimatter as a probe, but you do often measure products of antimatter decay or decay products that are antimatter themselves when doing it (depending on how much fidelity you need on the structure being imaged). I say pedantically because I assume you meant medical imaging methods and muon tomography doesnt have medical applications afaik
