Supersized scanner helps researchers explore the body and hunt down disease Published November 06, 2015.
When they were kids, Simon Cherry and Ramsey Badawi both wanted to be astronomers, unlocking mysteries in far off galaxies. That didn't work out for them. The pair still plan on unlocking mysteries but this time inside the human body. They've received a $15.5 million grant to build the world's first full body PET scanner. Unlike X-Rays and MRI's that image structure in the body. Positron emission tomography, or PET, images function on a molecular level. "We are able to say something about what the cells in the body are doing," said Simon Cherry a professor of radiology and biomedical engineering at the University of California, Davis. "How actively they are metabolizing, for example, or how quickly they are dividing. So taking cancer for example that could be tremendously powerful to see when you give a drug whether that shuts down the metabolism of a tumor," he added. The new scanner is called 'Explorer' and sets it apart is its size. Current PET scanners are only able to image parts of the body. This new device will be able to image the whole body in one go. "If you think about it really no organ in the body acts on it own," said Ramsey Badawi, a professor of radiology at UC Davis. "We are actually a system, a system of organs and all of the organs interact with each other. And we have never really been able to interrogate that with imaging before and now we are going to be able to look at that and that is tremendously exciting and it opens up a bunch of science that we really don't know where that is going to lead, actually," he added. What it could lead to is better and safer drugs, as well as more targeted diagnostic treatment for diseases, thanks to the unprecedented blueprint of the body this scanner could potentially provide.
