PET/Computed Tomography and Thermoablation (Radiofrequency, Microwave, Cryotherapy, Laser Interstitial Thermal Therapy).

Abstract Thermal ablation (radiofrequency, microwave, cryosurgery, laser interstitial thermal therapy) is being used more frequently as a local treatment of secondary but also primary cancers and benign lesions. It has a low morbidity and is repeatable. The problem is that computed tomographic scan has limits, and RECIST criteria are not applicable. The objective of this article is to summarize the usefulness and pitfalls of PET/computed tomography in detecting a relapse after thermal ablation as soon as possible.
