The role of 18F-fluorodeoxyglucoxe PET in malignant lymphomas

The conventional imaging procedure is CT in diagnosis of malignant lymphomas. However, nuclear medicine imaging has also had a prominent role. Single-photon imaging with 67Ga-citrate (67Ga) has been widely used for lymphomas. Positron emission tomography (PET) with 18F-fluorodeoxyglucose(18F-FDG) has gained a role in the staging and follow-up of lymphomas, largely replacing 67Ga as the nuclear medicine study of choice. 18F-FDG PET has proved useful in the staging, restaging, monitoring response of therapy and follow-up of Hodgkin disease and non-Hodgkin lymphoma. And the widespread use of PET-CT has also increased the sensitivity and specificity, reviewed the role of 18F-FDG PET in the management of patients with lymphoma. (authors)
