Actually I invent time travel next week.
I'd tell you how I know, but that has temporal side effects.

"A research team made up of atomic physicists " Aren't all physicists made out of atoms?

Pretty cool.

We have PET hypoxia agents. They have never made it to the clinic because they have never demonstrated sufficient clinical benefit to warrant use.

While interesting, it remains to be seen whether their findings can be replicated in a biological system with a dizzying array of micro-environments not to mention attenuation differences. I hope it pans out as  the hypoxia information could be beneficial and the reconstruction parameters for the PET could be tweaked to improve resolution.

As I posted either a few hours ago or several years ago, cold fusion has going to be ready in about four years for the past thirty or forty years.

Antimatter is not cold fusion.   It's ready right now.  What isn't, is our ability to create or store it in any meaningful fashion.  Particle accelerator slightly larger than the moon ought to help out with creating it, but storing it is still pretty hard I guess.  I mean I could make some room in my garage to help out, but I don't think it'll make that much difference.

However, Mr. Fusion, mentioned in the headline, was/is/will be a fictional at home version of cold fusion.

The first PET scanner was developed in 1970s. We have been clinically imaging patients since the 1980s. Before that imaging the two 511 kev photons from positron annihilation was done with coincidence imaging with NaI crystals.

This hopes  to extract more information from clinical scans and add to the radiomics data we already obtain.
