Investigate the science behind how doctors use radioactive drugs and PET scans to detect and diagnose diseases like Alzheimer’s and cancer.
--
Is there a way to detect diseases like cancer and Alzheimer’s before they advance too far? Doctors are using injected radioactive drugs that circulate through the body and act as a beacon for PET scanners. These diagnostic tools can detect the spread of diseases before they can be spotted with other types of imaging. So how exactly does this work, and is it safe? Pedro Brugarolas investigates.

Nowadays, we have combined physics, chemistry, and medicine to save lives. We've gone so far. That's why I don't understand why there are flat earthers and anti vaxxers.

Great animation! One addition. Why do Cancers take up radio contrast dye? because tumors have a rich blood supply and they consume more glucose/energy than normal cells as they divide fast.

Of course something as cool as a particle accelerator would also have a badass name ending in -tron. You don't wanna mess with the Cyclotron.

I've been doing a lot of research into particle physics and radiation (7th grade physics is boring) and I finally found a way to apply what I've learned. Watching a TED-Ed video always makes me feel great.

I love how ingenious this technology is. The sheer amount of time and effort required to create such a system must have been monumental. Well done, everyone involved.
