What are the in-vivo imaging techniques
The first of the in-vivo imaging techniques, computer tomography (CT) scanning, came on stream in the early 1970s. As technologies developed, and the value of scanning became clearer, it was soon followed by other procedures including PET (positron emission tomography), rCBF (regional cerebral blood flow) and MRI (magnetic resonance imaging). The common feature of these procedures is that researchers can produce images of the structure or functional activity of the brains of living people
