Besides, found out disagreements help in a better management of quality criteria for the right use of equipments, and also decision making on new technologies acquirement. Given results have been very useful for training specialists belonging to the medical institutes, and works as background for the application of the document “Audits on Quality Management in Nuclear Medicine Practice.
