He won the Nobel Prize for his work on the development of PET scanners. PET stands for positron emission tomography, which is a nuclear medicine technique used to create images of the body. PET scans use radioactive isotopes to measure the amount of glucose (sugar) in the body. The PET scan was invented by Lauterbur in the 1980s, and it is still widely used today.
