Positron emission tomography (PET) provides a unique technology for establishing the relationship between the plasma concentration of a compound and the degree of target engagement in tissues such as the brain, which are not accessible by other methods.
Positron emission tomography (PET) provides a powerful means to non-invasively image and quantify protein expression and biochemical changes in living subjects at nano- and picomolar levels.
A recent study by Daisne et al.[ 3 ] showed that CT and MRI overestimate the size of the primary tumour, and [F]FDG PET provides a smaller but more accurate assessment of volume.
PET provides an excellent opportunity to assess brain activity in either the resting state or when the subject performs a task or is exposed to a stimulus.
C-raclopride (RAC) positron emission tomography (PET) provides an in vivo measurement of striatal post-synaptic dopamine D2 availability.
In a recent PET study using F-Florbetapir with 74 HC and 29 AD patients with terminal disease, demonstrated a high correlation between in-vivo tracer uptake and the presence of β-amyloid at autopsy, as well as 96% sensitivity and 100% specificity in distinguishing HC from AD, thus suggesting that F-Florbetapir PET provides an accurate and reliable assessment of amyloid burden [ 69].
"The unique life-enriching bond, the love and companionship a truly special pet provides us a unique sense of comfort and life-enriching fulfillment which is nearly impossible to extend beyond your pet's natural lifespan.

I don't know if all humans are as gullible as I am, but it's now my suspicion that my brain would have no qualms about forming a bond with a virtual pet, provided the AI were good enough to avoid breaking the illusion.
