Pet imaging

FDG-PET has significantly contributed to improve the management of most aggressive and Hodgkin lymphomas. Although more heterogeneous, FDG avidity has been demonstrated also for indolent lymphomas, leading to increased use of functional imaging in this setting. In this chapter we review available data about the contribution of FDG-PET for staging and response assessment and for the identification of histologic transformation of follicular lymphomas and of other low-grade B-cell lymphoma subtypes.
