case_images: Thoracic FDG-PET CT prior to treatment (left side) and after 5 cycles or Rituximab (right side). Lesions marked with arrows. The luminous structure in the lower right picture is the left ventricle, which shows an increased metabolism compared to the right picture, because it is contracting. This FDG-PET accumulation has nothing to do with the metabolism of the tumor cells.
