  • 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.

    It is also relevant to know that aside of F-18, produced with accelerators, the most widely used radioisotope for this kind of diagnostics (with tens of millions of procedures per year) is Technetium-99m, which is produced in nuclear reactors.

    So if I understood correctly, we can determine if there's a tumor when a certain area has accumulated FDG? Wouldn't it be possible to see it when blood has accumulated on that area? (Since the tumor has blocked the blood flow)

      The scan doesn't detect blood, and i don't think cancer doesn't stop the blood flow really, just sucks up the nutriens and other stuff that it's carrying(feel free to correct me)
      Watch the video how the scan detects the radiation off the accumulated stuff inside the cancer please :)
