Abstract:
PURPOSE: The authors evaluated the usefulness of the positron emission tomography (PET) with fluorine-18-tluorodeoxyglucose (8F-FDG) in initial staging, reevaluation after radical therapy and diagnosis of recurrence for non-Hodgkin's lymphoma, compaired to conventional imaging studies. MATERIALS AND METHODS: FDG-PET (ECAT Exact 47, Siemens) and conventional chest X-ray and computerized tomography (CT) were studied in patients with non-Hodgkins lymphoma. RESULTS: There were 17 patients (13 male, 4 female). Age was ranged from 18 to 62 years (median 49). By histological subgroup, diffuse large cell were 8 cases, peripheral T cell were 2 cases, diffuse mixed was 1 case, follicular mixed was 1 case, Burkitt's lymphoma was 1 case, Hodgkin's disease were 3 cases. The aims for PET were the initial staging work-up in 7 cases, the reevaluation of residual disease after radical therapy in 7 cases, the diagnosis of recurrence after complete remission in 3 cases. Between PET image and the conventional image, there were 3 cases with discrepancy, 1 case for initial staging work-up and 2 cases for the reevaluation of residual disease after radical therapy. Among the 3 cases with discrepancy, the 2 cases for the reevaluation of residual disease after radical therapy revealed that PET image reflects the involvement of lymphoma more accurately than the conventional image. CONCLUSION: The visual analysis of FDG-PET would be helpful in determining the residual disease of lymphoma after radical therapy.
