PET scans of the minimally conscious state
Professor Andrea Soddu and colleagues have shown that PET (Positron Emission Tomography) scans identify patients in a minimally conscious state (MCS) far more accurately than other imaging technologies.
This conclusion came as a result of clinical validation studies between 2008 and 2012 in Liege, Belgium. One interesting aspect of PET technology is that because the exposures can take many minutes, the resultant scan shows the accumulated activity within the brain over that time period.
