Kaplan-Meier curve of SUVmean with a cut-off value of 5.15.

There was a mass in antrum of stomach on transaxial CT (A), PET (B), fusion (C) and MIP images (D) (arrows) of a 60-year old female patient with primary gastric lymphoma of DLBC type. She had metabolic tumor parameters of SUVmax: 11, SUVmean: 5, MTV:34 cm3, TLG:150. Her outcome was excellent with a DFS and OS of 111 months.

61-year old female patient was diagnosed with primary CNS lymphoma of DLBC type. There was a mass in right periventricular region adjacent to right thalamus on transaxial PET (A), CT (B) and fusion (C) images (arrows). She was in serious risk because of her high metabolic tumor parameters (SUVmax: 35, SUVmean: 25, MTV: 425 cm3, TLG: 2543) and died of the disease 11 months after the diagnosis.
