From: A comparative study of standardized quantitative and visual assessment for predicting tumor volume and outcome in newly diagnosed diffuse large B-cell lymphoma staged with 18F-FDG PET/CT

Metabolic tumor burden assessed on a VAS scale with representative examples of patients graded as 1, 5, and 9 (a). All reviewers used these examples to grade individual cases in the study. b An example of a patient with a poor prognosis based on the widespread peritoneal lymphomatosis, bulky disease, and high metabolic tumor volume. Pointedly, the peritoneal lymphomatosis may be difficult to accurately quantify using semi-automatic tumor delineation tools whereas the severity of disease is readily perceived by visual inspection using a maximum intensity projection FDG PET/CT. c A patient with limited mediastinal disease used as an example of a patient with favorable prognosis
