Brain Scans That Spy on the Senses

I know we don’t talk a lot about nuclear medicine I thought I would post one or two for us Rad Health’s out there.

With the use of PET scan (positron emission tomography) and the use of radioactive water, scientists are now starting to image the brain as it actually functions. When something like head phones we put on or pictures shown. The area of the brain that was being used had increase blood and radioactive water flow and showed up on the images. There is also much excitement with a new MRI method called an fMRI or functional MRI and requires no use of radiation for a higher resolution image. From this information it was even able to be seen the response of different fingers being touched. There is said to be much promise in this new technology.
