Answer

Functional imaging with positron emission tomography (PET) has become an important diagnostic and prognostic tool in the management of patients with various subtypes of lymphoma, such as DLBCL, Hodgkin lymphoma (HL), and mantle cell lymphoma (MCL). Most academic institutions recommend routine PET scanning to complement staging and posttreatment evaluation of all patients with aggressive lymphoma. Retrospective studies have demonstrated that midtreatment and/or end-of-treatment PET scanning provides strong prognostic information in terms of progression-free survival (PFS) and overall survival (OS). The adequate timing for PET scanning for response assessment is a subject of controversy and recommendations vary among academic institutions. [26]
