[en] Objective: To investigate the diagnostic value of ¹⁸F-FDG PET/CT on Hodgkin lymphoma(HL) recurrence according to Deauville criterion. Methods: Retrospective analysis was performed on 24 HL cases for a period of 5-27 months after treatment. These patients were clinically suspected of recurrence. Results of ¹⁸F-FDG PET/CT imaging according to Deauville criterion, lymph node biopsies, and(or) bone marrow biopsy pathology were analyzed and compared. Results: Seventeen cases of recurrence were confirmed by pathologic findings. Three cases of lymph node reactive hyperplasia, 1 case of lung cancer with mediastinal lymph node metastasis, and 3 cases without recurrence were recorded. Sensitivity, specificity, positive predictive value, negative predictive value, and accuracy were 100%, 50%, 85%, 100%, and 87% for ¹⁸F-FDG PET/CT on HL recurrence diagnosis. Conclusion: ¹⁸F-FDG PET/CT is of important clinical value on the diagnosis of HL recurrence according to the standard of Deauville criterion. (authors)
