Researchers have found that PET may become one of the most preferred imaging methods for the individualized therapy

Researchers have found that PET may become one of the most preferred imaging methods for the individualized therapy mainly for disorders which are caused by addictive behaviours. Researchers who use positron emission tomography (PET) have recently validated the well known theory that individual personality traits like reward dependency is connected to brain chemistry.

For the study, the researchers had evaluated some 20 odd males with no history of any substance abuse. The participants received "Fluoro-ethyl-diprenorphine“a radio-labelled chemical that easily binds to the brain's opiate system, which occurs naturally, and then the participants were subjected to a PET scan. The scans were then compared with the results of each individual participant's ‘Cloninger temperament and character inventory’. It is a questionnaire system that assesses a person’s personality based on 4 dimensions: harm avoidance, novelty seeking, persistence and reward dependence.

The results vindicated the long-held theory that there was a correlation between reward dependency and the brain chemistry. In light of this, the researchers feel that they foresee PET to become a preferred imaging method in the near future for individualized therapy in the whole gamut of disorders which are caused by addictive behaviour.
