Deauville Criteria

The Deauville criteria are a set of standardized imaging criteria used to evaluate the response to treatment in patients with lymphoma, particularly Hodgkin's lymphoma and aggressive non-Hodgkin lymphoma. They are primarily based on the use of positron emission tomography (PET) scans but can also involve computed tomography (CT) imaging. The criteria classify the metabolic activity of lymphoma after treatment into five levels, which helps clinicians determine whether a patient is responding to therapy.
