PET is the same as PET/CT for restaging lymphoma – pro

PET scanning has well recognized utility in staging and restaging lymphoma. It is now covered by CMS and recommended by recent literature. In regard to PET/CT, in a recent study, the addition of PET/CT to CT changed the management decisions in approximately a quarter of NHL and a third of HD patients, mostly in early disease stages. Thus, PET/CT performed as the initial staging procedure may well obviate the need for additional diagnostic CT in the majority of patients. Based on this, I consider PET/CT to be the same as PET for the purposes of this review. NCCN recommends PET for restaging of several lymphoma subtypes, such as Peripehral T-cell and large cell lymphoma.
