Lymphoma is a malignant tumorous disease affecting immune cells which are responsible for protection against infections. It is associated with uncontrolled growth and proliferation of abnormally functioning white blood cells. The disease may be present primarily in lymph nodes, spleen and bone marrow, but it can develop in other organs as well and can spread to other tissues. There are two main groups of lymphomas: Hodgkin’s-disease and non-Hodgkin lymphomas. The type of the disease is usually determined by removal of the lymph node and with histological sample taking. The optimal therapeutic method is determined by the type of the disease, the extent of the process and its stage. Hodgkin-lymphoma is nowadays one of the most successfully curable tumors. In the non-Hodgkin lymphoma group there are several different subtypes, some of them can be successfully treated, while others can be symptom- and complaint-free for a long time.


The role of FDG PET-CT in the diagnostic process of lymphomas

  • Its application is primarily wide-spread in the diagnostic process of aggressive lymphomas.
  • Before starting the therapy it is used to judge the extent of the disease, to detect involvement of lymph nodes, organs and tissues and to determine the stage-classification of the disease.
  • It is used for choosing the optimal lymph node for histological sample taking.
  • To assess the early therapeutic response a short time after initiating the treatment.
  • To assess the therapeutic response after therapy and to characterize residual abnormalities (differentiation of active cancer tissue and scar tissue).
  • It is used in the detection of recurrence.
