OBJECTIVE: To explore the possibility of evaluating the short-term therapeulic effect of radiofrequency ablation (RFA) in cancer treatment by positron emission tomography.METHODS: The radioactivity intensity of the tumor was detected by PET before and after RFA.RESULTS: Radioactivity blank was observed in all 33 cases with 54 lesions, indicating the elimination of the tumor was destroyed.CONCLUSION: PET is of great significance in evaluating the short-term effect of RFA.
