Among these, methodological aspects related to the preparation of the patient and his/her own physiology, and also those related to the quantification and processing of the PET study which can account for up to 20% of the variation obtained when acquiring the SUV value [1].

Specifically, little is known about the interaction among situational, methodological and learner variables and how, collectively or individually, each of these factors mediate the effectiveness of feedback.
These include inconsistency in psychometric scales and constructs used, the lack of validity and reliability in many of the measures, small sample sizes, and no sub-categorization of anomalies among other methodological errors [23].
