Objective and accurate evaluation of treatment response in interim (iPET) and end of treatment (ePET) PET/CT is one of the most important parameters of patient management. In this review, standardization studies used in the evaluation of treatment response with PET/CT in lymphomas, the importance of iPET and ePET in patient management, metabolic tumor markers and pitfalls that can be followed in PET/CT after treatment were evaluated. © 2021 Nuclear Medicine Seminars.
