Abstract: Cervical cancer is one of the most common malignancies in women. PET and PET/CT offer the combined anatomic and functional imaging， have high specificity for detecting tumor or metastasis lesions，and have been used to localize areas of standard fluoro-2-deoxy-D-glucose（FDG） uptake value（SUV） and help to assess the metastatic potential without impact of anatomic change after surgery. Therefore， PET and PET/CT have more advantages than traditional radiologic examinations in detecting lymph node and distant metastasis in patients with cervical cancer and are useful to identify recurrent cervical cancer， evaluate the prognosis and make the treatment plan. However， a larger prospective study is still needed to confirm the effectiveness of SUV in clinical practice and whether PET and PET/CT can take the place of other imaging methods and clinical staging procedures.
