Unlike CT/ MRI, 18F-FDG positron emission tomography (FDG-PET) provides a novel means of imaging malignancy and could differentiate benign tumor from malignancy by functional assessment. Recent studies demonstrated higher accuracy of FDG-PET scan for the evaluation of metastasis in patients with several types of cancers when compared with CT scan or MRI. But, only a few reports concerned the usefulness of FDG-PET in cervical carcinoma.
