Abstract:
Objective:Position emission tomography/computed tomography(PET/CT) is a new bio-imaging system which is combined metabolic with anatomic imaging.This study was to compare the accuracy of conventional staging methods(including computed tomography,ultrasound,magnetic resonance imaging,and detection of bone marrow) with that of PET/CT for lymphoma staging and re-staging. Methods:A total of 42 patients with lymphoma diagnosed by operation or biopsy,received conventional and PET/CT staging.The accuracy of these two methods and their impact on lymphoma staging were compared.Results:The accuracy of PET/CT scan was 95.2%(40/42),and that of conventional staging was 78.6%(33/42).The detection rates of internal lymph node were 97.1%(66/68) and 88.2%(60/68),respectively.The detection rates of outer lymph node were 91.7%(22/24) and 58.3%(14/24),respectively.Compared with conventional staging methods,7 cases were up-staged and 2 cases were down-staged by PET/CT,which led to the change of therapy in 8 cases.Conclusion:PET/CT scan is more sensitive and accurate than conventional staging methods in staging and restaging of lymphoma.
