Using radioactive drugs to see inside your body - Pedro Brugarolas

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.
